As a mid 40s person also, my advice: drink plenty of water, clean the kitchen every night, don’t try to time the market, forgive your past self for being an idiot.
I keep thinking about cleaning the kitchen every night (I just turned 30). The more I think about it, the more I think it's a good advice. I still need to forgive my past self for being an idiot, though :)
Short but brilliant. Well done.
I'd add: try to sleep well. It adds up.
So much to do and so little time. But you’re right, it’s so important.
