It's ok to contribute 10 weeks for another framework or pet project, right? However math tell if you do it 100 times 100% focused on one by one thing, you might run out of time and wont be able to cash out on your expectation.
How do you personally feel about the next 1000 weeks? Any decent timeline lifehacks?
You could get hit by a bus any day. You have to find a balance in your life where you are happy having lived it, even if it ends tomorrow, while also doing what you need to do to provide for yourself and your family, and enjoy life if you live to 100+ years old.
I've tried and failed quite a few times (10+), and my current experiment - while I think it's a successful one, time will tell.
One thing I would suggest is you read "The Mom Test" book -- I think it'll serve you well in the long run (it's about marketing, and you'll need to do that if you develop your own products).
There are many efforts to bring life long work into a compact number. https://80000hours.org/ is quite a famous one.
