Quit my job to start a company. Failed, but learned a lot of important lessons. Got back to a well paid job. Probably most important - got back to a very good shape.
- focus on the product - doing anything else before having at least an mvp is dumb
- focus on one thing at a time
- never lie to yourself
- we usually hugely overestimate what we can achieve in a short period of time, but also hugely underestimate what we can do in a long one
- being in good shape greatly improve my mood and performance at work
- don't mistake activity for achievement
And some more. Of course most of this stuff is obvious and I have always thought I knew them. This was in theory - this year I have 'learned' them the hard way.
