Actually, any sort of career advice.<p>I'm a 28 year old 4th graduate student at the terminal end of my PhD (at a top 10 in the US if that matters) in a computational physics subfield (less than a year left). I have a few startup ideas I'd like to try and pursue but the problem is at the end of day I'm completely wiped energy-wise. I am taking a two courses (a grad course in machine learning and time series analysis) which may be a part of the problem but those are two things I've always wanted to learn.<p>I'm completely dispassionate about my research which I'm really just cranking papers out using well established methods and not focusing on a single problem. I publish a paper and move on to the next thing since we promise different things to different funding agencies.<p>I've though about leaving my program because I'm so dispassionate about the work. I really just want to build something cool, interesting and useful.<p>I'm curious if anyone else has been in the a similar situation.
Finding the time for experimenting while doing ____ exhausting, responsible thing, is incredibly hard. It really has to be a matter of life and death for your soul.<p>But here's the thing, finish your PHD. You'll be in the same situation in the "real world", when you have to work a job you don't really, really care about, and find time to explore other things you do. So start learning how to balance that now, while you've got the 'cranking papers out' down.<p>A few practical tips:<p>If you're wiped at the end of the day, get up an hour earlier and use that time instead.<p>Weekends.<p>Set very small, meaningful goals / questions / experiments you can hit. When you have to make time, it's all about momentum. If you get bogged down / unmotivated on your side projects, you don't stand a chance.<p>Good luck. Persevere.
If you're cranking out papers, then you should have enough papers to finish soon; in that case, just finish your Ph.D. and move on. Tell your advisor that you want to graduate within the next year, and that you have the papers to do so. Like it or not, the credential can open up doors for you in the future in unexpected ways, and you're so close to it already. (If you were, say, a 2nd-year student and felt this way, then leaving would be a much more feasible option.)
I didn't go to grad school and can't relate to your situation, but sounds like your best bet right now is: 1) Find the path to finish your degree asap (you already spent a number of years on it, shouldn't throw it away), then 2) land a job in a place like Google and make some good money.<p>It sounds shallow, but having a lot of money rolling in to your bank account on a regular basis for the first time of your life will do a lot to you on a psychological level. You'll need that boost in both the emotional and materialistic sides. After a year or so of that, you have more options and can think about life or building cool stuff a little more.<p>The one thing I <i>can</i> relate to you on is feeling wiped at the end of the day. I worked in a startup-turned-unicorn a number of years ago. The first couple of years was extremely fun and exciting. A few years in, the company IPO'd, and work gradually became incredibly draining and boring. The worst part is, I had all these ideas about cool things I wanted to work on, but was too drained to work on them. I left that company after a few years and have been through founding a startup, failing and back to a regular employee developer since then. Through these years I have never lost passion and energy since. I guess the point of that anecdote is that I know how it feels being wiped at the end of the day, but I had financial security to allow me to leave it and start over. You'll want to get to financial security first.
Random remarks from the internet:<p>Not having the energy to pursue an idea is a useful filter. It means pursuing the idea is theoretically exciting but not actually exciting enough to actually pursue. That's most ideas for exceptional people and pretty much all ideas for most people. Machine learning and time series analysis pass the filter. Keep riding that bus for now.<p>Your day job of doing dull research is just a day job that advances your career opportunities, and having a PhD statistically increases a person's career opportunities. Grad school often ends with a 'death march' to just get the damn thing done. The only thing that is guaranteed is that not finishing means no PhD. Short of severe mental health issues, there's not much upside to quitting with only a year left.<p>Good luck.
Finish the PhD. Today anyone who discovers anything does so after their Ph.D. A Ph.D. is just a work sample really. I regret not finishing, then again I couldn't figure out a path to get there despite 4 papers. Then take a vacation! After that there is a lot you can do you can get a job programming, as a quant etc... I would work for a bit to see if you enjoy it. You can also postdoc or do other academic things if you want to continue in research. You can do applied research or R&D as well.<p>But first take that vacation! Sometime you have to get out of your situation to get perspective.
This guy created a very epic game while doing his PhD: <a href="http://www.ultimaratioregum.co.uk/game/" rel="nofollow">http://www.ultimaratioregum.co.uk/game/</a><p>I imagine he must have gotten tired for similar reasons as you and just wanted to build something.
>I've though about leaving my program because I'm so dispassionate about the work. I really just want to build something cool, interesting and useful.<p>Suck it up. "Cool, interesting, and useful" comes after you've made enough money to pursue passion projects, if you get lucky in academia, or if you get lucky on the job market.<p>Sorry. You should finish your PhD because it sounds like you've done a good number of good papers and <i>deserve</i> the degree already. Beyond that, you need to think about a market niche.
AI researchers are in high demand according to recent news stories. If you can stick it out and really build your skills in AI and machine learning, you will get the opportunity to work on all sorts of cool things in the private sector.
I strongly believe that if you want it bad enough, you'll make time/effort for it. If not, then it simply isn't important enough for you - and that's perfectly ok.
If you want to get out of academia, start learning how to actually build things. I mean sure, get your PhD. But in the meantime start programming, designing, and acquiring skills that can propel your career outside of academia.<p>I wouldn't recommend starting a business before you have any marketable skills.<p>It's never too late to switch fields. I know people who've done it in their 50's.<p>What would you like to do anyway?
