> Seek meaning, not happiness.
Hold your horses a bit here. Just because some mental model works for your, please don't do blanket statements for entire human civilization.
I for example pursue many utterly selfish hobbies without any proper meaning to me or anybody else, full of objective dangers that can kill me in case of lack of attention (or pure bad time at bad spot situation), last time this Sunday (ended up with scratches all over me after some nasty snow field slide, albeit this is very rare outcome).
The only meaning of those things (hiking, climbing, diving, paraglide, ski alpinism etc.) is feeling 200% alive, being extremely content with my life which can be described as... you get it... happiness. Climbing to the top of some peak doesn't have any proper meaning, it has been done 1000s before and will be done after me, the only meaning is how it feels during and after the adventure.
Maybe its just juggling words and we both mean same thing at the end, but I know far too many people technically unable to find long term happiness, to see how that sucks. Most of them are these highly-driven super-competitive types that have lives that look great on outside... but only if you don't know them very well.
