In regards to the concept of caring about your future self, a simple example being not staying up late drinking so in the morning you don't/your future self doesn't feel awful for work. Is there some phrase that handily captures or illustrates this? Especially if its something that somehow emphasizes the building of the habit and return over time (the more you don't stay up late, the more consistent/reliable for work you are).
The closest I could think of was someone I once heard using "cast your bread upon the waters" and describing how the waves bring it back. Presumably you could consistently cast bread and so receive consistent bread returns at opportune moments but who wants soggy bread (or maybe I don't appreciate this phrase well enough).
To be clear I'm not thinking in terms of literal investment, or at least basic savings/interest idioms don't seem to suit. "A penny saved is a penny earned" for example doesn't quite seem to fit, but if there's something relatively broad that's similar I'm open to it.
This is also not a one time thing like What is it called when you do something once and benefit from it for a long time or forever
