Life seems to boil down to this: you want something until you get it, then you want something else.
The trick is not to stop wanting more and be content with what you have, nor is it to never be happy with what you have and let your ambitions consume you.
The real cheat code is to enjoy what you have while pursuing what you want, remembering that everything you now have was once something you wanted but could not yet have.
Let your ambitions drive you, but do your best to enjoy what you have built and acquired as much as you hoped you would when those things were still out of reach.
