I limit my social-media use to 30 minutes a day- each day at a particular time. In other times, I rather stare at a wall or eyeball the floor, even if I am waiting in a queue. This somehow improves my cognitive tasks a lot. I don't know why. I learned it from Cal Newport's "Deep Work".<p>I also use Pomodoro timer. It works well with me. Without Pomodoro, I can do really focused work for maybe two hours a day max.<p>With Pomodoro, that increases to five, sometimes (very rarely) six hours a day.<p>I listen to music. Especially Bach. I cannot not do some good work when I am listening to that good music. It's just me, I know.<p>I exercise 4/5 times a week (~30 minutes a session). It really helps with mood, energy, and concentration. I am sure this is not placebo.<p>I meditate for 30-45 minutes each night. Without fail. Significantly improves concentration, focus. Meditating has made me realize, for the first time in my life- what I actually want with my life. I am much more calm, composed, and relaxed.<p>Routine helps and so does timeboxing. Doing specific things at specific physical places at specific time- and having set time- that helps immenesely. So, it's not JUST pomodoro, but timeblocking + time-tracking w/ pomodoro.<p>I also learned from Deep Work to have clear work-life boundary. Made my life much better. I turn off from work at a certain time. Knowing that I will <i>have to stop working</i> at that time makes me more focused as well. Where blurry or non-existent boundary b/w work and life makes you think you can slack " now" and work "later". Happened with me.<p>I am trying time-logging now. Too much friction, but I am sticking with it.<p>I am still bad with interactive decisions in my life, like providing in-place answer, seeing into several steps into the future, etc. I was always considered very intelligent, but an average person could always wipe the chess-board with me. I want to master Chess. I think it will fill a gap in my life. Surprisingly, Factorio has been a blessing. It improves my thinking, and I plan to play it more.<p>GTD method did not work well for me. I guess it is more geared towards suits, MBAs, managers, etc. Not for intellectual knowledge workers working on the cutting-edge.<p>Two books that immensely helped-<p>1. <i>Deep Work</i> by Cal Newport<p>2. <i>Pragmatic Thinking and Learning</i> by Andy Hunt<p>Two books for meditation-<p>1. -The Mind Illuminated* by Culadasa et. al.<p>2. <i>Mindfulness in Plain English</i> by Bhante Henepola Gunaratana<p>Learning about Buddhism and Buddha's teachings have also made me an overall better human. I would recommend <i>What The Buddha Taught</i> by Walpola Rahula.<p>Remember that reaching peak focus is a trial-and-error experiment that lasts for months or years. Many habits that I have today- I found them through deliberate, vigilant trial and error. Keep with it. Answers for different people are likely different.<p>Btw, also listen to Huberman Lab Podcast.
