If you have 5 years savings, and a passion for something else, and you think (hope) you're talented enough to pull off running your own business, then go for it. You'll always regret not doing it when you think/hope you are capable of doing it. Even if you fail, you'll "graduate" with a ton of learning plus you won't face that regret. I wouldn't recommend you burn all 5 years worth of savings though. Set a year aside, and set some benchmark that you must reach by the end of the year. If you don't reach that benchmark/goal, go find another job that will be more tolerable for you.
