Recently, I've read about a mental framework called "Regret minimisation". With regret minimisation, you ask yourself, "Would my future self in x minutes/days/weeks/months/years regret doing this or regret not doing this?", and based on this, you do what would be preferable for your future self.
A short-term example might be if you are considering eating a sugary snack, you ask yourself, "Would my future self in 15 minutes regret this?". If the answer is yes, then you do not eat it; if the answer is no, then you do eat it. Or if you are sitting on the sofa, and consider, should you continue to scroll through various apps on your phone, or should you get up and practise xyz? You ask yourself, "Which option would my future self in 1 week prefer?" and go with that.
Typically, our current self is more likely to pick an option that is more comfortable in the moment, implicitly delaying anything that is immediately uncomfortable to our future self. However, the option that would optimise happiness and comfort for your future self is typically the one that is more uncomfortable in the moment, and thus less appealing to your current self. Thus, it is better to consider what your future self wants in any scenario and act accordingly.
I prefer to think of this as optimising for your future self rather than minimising the regret of your future self.
Related to this is a great quote by Abraham Lincoln, "Discipline is choosing between what you want now and what you want most". Your current self is trying to choose what you want now, which has some benefits now that your current self gets to enjoy, but greater costs later that your future selves suffer. However, your future self is trying to choose what you want most, which has some costs now that your current self suffers, but greater benefits later that your future selves enjoy.
