If the extra money is enough you may have enough to become your own boss after some time spent being miserable.

I've been quite miserable whenever I worked as an employee (I carefully picked the companies I worked for and I don't really have many complaints - I just can't stand company politics, power plays and stupid decisions from above) but I used my time as an employee to save some money and use paternity leave to build a family. Also, as a sleepless parent, my brain is not in top shape and I'm ok with doing what I need to do to collect a paycheck.

Now, those 5 years being miserable will translate to buying a property in cash somewhere with nice weather, lowering our expenses tremendously (more than half is rent right now) and allowing us to live off some almost passive revenue stream (think, 1 man micro-saas). We're planning to use the free time to build more products and edge ourselves against the risk of not being able to afford our lifestyle and have to go the employee route again.
