The usual advice is to pick up a hobby like sports, weight lifting, woodwork or martial arts. Definitely do that.

You haven't mentioned your location but I assume you're in the US. You were great at your job in FAANG and have a large amount of savings. Consider moving to continental Europe and work for a FAANG or similar company there to improve your work-life balance and reduce cost of living.

Take a look at Germany, Netherlands or Sweden. You don't have to learn the language before moving there, you get more vacation days a year, longer parental leaves (in the case of Sweden you may qualify for the paid parental leave even if have a small child who was born before you moved to the country), and good public transport, no need to be stuck in traffic jams. Free healthcare and education are also a plus.

Good luck finding your mojo again!
