I think you made a false dichotomy between thinking of the future and mindless indulgence.

You can be mindful of who you are and what you want now.

A life of always suffering for tomorrow is arguably as bad as a life of mindless indulgence.

You can get to the end without ever enjoying it.

It is better to not want chips than always want chips and restrain yourself.

It is better to enjoy exercise than suffer through it.
