Based on my personal experience (SlashMap - fairly successful Slack plugin), I’d recommend trying to verify an idea before giving up your full-time job. For instance, you can start with a landing page to do so. I must confess that combining full-time work with a side project was challenging for me and affected work-life balance heavily in my case, but it may be the best choice if you’re not ready to quit your current job. Working on a side project only in your free time will probably significantly slow down the progress, but you can think of finding a partner to help you with it (if the project succeeds you’ll probably need a partner anyways). Opinion and complementary skills of another person may be keys to success as well. I’d say that if you really believe in your idea, it’s very likely you’ll find a way to verify it before quitting your current job. Good luck!
