Cravings vs. Self-Indulgence vs. Self-discipline | Artful Balance

Is self-indulgence always bad, and is exercising self-discipline always good?

That depends.

After indulging this craving, will I be able to divert my focus back onto my main goals (especially the important-non-urgent, long-term ones)?

Or after I indulge this craving, will I only want more and be unable to stop myself from getting more?

And as for discipline, would carrying on lead to the production of a thing I feel proud of, or am I just paddling in circles in the name of principle?

There are cases that call for less discipline, not more. Discerning what each moment calls for takes effort and balance.
