I found it helpful to go in with low expectations.
I was listening to a lot of podcasts about bootstrapping while I was still at Google in 2017-2018, and even the big success stories usually had 5+ years of failing or succeeding only marginally. So, I went in with the expectation that I'd probably fail for the first 5 years, and so there wasn't that feeling of disappointment from not earning much the first few years.
I also had a lot of lucky conditions that made it easy to take the risk at the time, including no family to support, lots of savings, low expenses.
> I'm also quite lucky that I was aiming for lean-FIRE before I left Facebook, so I have the luxury of being able to keep at it, but sometimes it is demotivating seeing peers / others.
Yeah, honestly I do sometimes think, "Wow, if I'd stayed at Google and kept getting that comp (which was about 50% equity IIRC), that would be a lot of money." But I also am very pleased with my life now, and I know I wouldn't have enjoyed my job nearly as much for the last 8 years had I stayed an employee. And that's a huge amount of my life to not do what I'd like to do.
