what works for me (and it works well):
- having an unrelenting feeling that i need to live up to my potential, otherwise i'm not only disgracing myself but all of humanity
- asking myself, "why am i doing this?" ... a lot (as a way to continuously ensure my actions are moving me toward my goals).
- when given a choice between being productive and not being productive i remind myself to "just do the right thing."
- reminding myself of those who had to bust their asses to achieve greatness and ignoring the proverbial lottery winners (i.e. those who barely had to work for success).
so far so good. i'll be able to report more fully on the results in about 5-6 years.
edit: a pre-requisite for this type of list i should add is having a goal or a series of goals; the absence of which we just end up chasing instant gratification and transient needs.
