I hate to agree with your parents BUT....<p>If you continue with your miserable job things will take longer, and your job will get in the way from time to time. However you should funnel that misery into motivation into building your app. If you are single, don't have kids you can do this easily, nights and weekends. It will mean giving up some hobbies and not going out with friends but I like your odds. The money you saved should not be spent on living without a job for 6 months, pay someone to help you build your idea. The risk is low as it seems unlikely you would move in with your parents if you had a wife and kids. The flipside of this is;<p>You build your business, you finish it and then... maybe you don't have any customers, or no revenue, and the panic of "I have no job and my product is failing", this is a pretty terrible and terrifying feeling.<p>For the record I've met 2 people who opted for what you are proposing (quit job, work on project full time) and they both went through the panic of "my project is done and I have no or insufficient income!" And what happens if you don't finish? What happens if you hit a snag? Even if you do everything right does not mean you will have enough paying customers after 6 months. I feel like you are setting yourself up for failure without a net. I know it works out for some people, but I'm only playing the percentages here and I feel like you are more likely to be on the losing end.<p>I on the other hand have a wife, 2 kids, am the primary bread winner and have built my project after hours. It has been slow going and I have no revenue. I've lost a lot of sleep. I've struggled with marketing. However I still have confidence in what I'm doing, and while it takes more time for me to make changes and market on my own I prefer being where I am. My only complaint is I can't market much from 9-5. I've resorted to making cold calls at lunch, but I feel like I'm doing the right thing (I don't have much of a choice really with the kids and family, but still). My project may be a total failure but I still have the satisfaction of building something myself without the panic. All I lost was sleep, and time with friends. I have no regrets.<p>For me there will be no dread fueled panic (or panic fueled dread) from the feeling of "I have a project that is not generating enough revenue and I have no job!" Granted I can't afford to quit. But while I've made some unwise decisions in development(learning a new language/framework to build a web app) and struggled with some decisions I don't feel the pressure that those bad decisions ruined me, they were learning experiences. Please do not quit your job.<p>If I can do it after hours you surely can do it. Listing to Rob and Mike from Startups for the Rest of Us podcast, and they both worked on their startup until they had enough revenue to quit. I would trust their advice before mine. Definitely pay someone else to help you, which will move things along faster. You are young and the risks are low, it's a worth while investment.<p>Good luck man, sorry to come out on the same side as your parents.
