Starting a family is definitely the safest bet, probably long term too because these ideologies tend to lose their appeal over time.
But hey, I don't even seek happiness myself. I'd be glad to just know WTF all this was about before I die. Being some 10^28 particles out of 10^80 particles in a weird universe which doesn't seem to have any obvious purpose on one hand, and yet we're in this specific one and not in any other.
On the one hand it's so mind bogging huge and yet on large scale everything is pretty predictable, and the only interesting calculation as far as we can see in universe is actually right here. Humanity could explode into the Galaxy or it could die silently and predicting it is harder than the most complex physics of any known star.
