upon dealing with a certain problem, try to figure it out using this approach:

in five years, will it still matter?

i believe we will see many 'no's answering this question. i know it's difficult (and i mean it i really know i'm not just bluffing) but if the answer is a no then just try to put aside the problem and not to give too much concern to it... just a waste of time you see. in five years you will laugh at yourself at how foolish you are, to fuss over such a matter.
