Started working on https://nota.io https://nota.io while employed as full stack dev. The idea actually came from my day to day workflow. Quickly I found that I had trouble focusing on the job that was actually paying me and all i wanted to do is build my app. So I quit (my employer totally understood my motivations). That was 6 months ago. Now I've launched a few week ago and I am realising that I planed a bit short budget wise, so soon I am afraid I'll have to go back job hunting. I wish i had plan for more slack. The lesson that i've taken form that is that if you want to build a software that you are passionate about soon enough it will take all your focus. So do plan on that. Validate and plan as much as possible while keeping your day job and when you are as ready as you possibly can just take the dive! Good luck.
