When was the last time you said – “Ah it doesn’t matter, I’m never going to see the person ever again’ or ‘ah this module doesn’t matter, there are 7 more semesters to go to prove myself..’
Short term thinking is very common in our society (many times encouraged as well). It is a convenient way to escape responsibility for actions that will have a long term impact (be it good or bad). I have found myself falling into the same trap many times, only to have a trusted mentor pull me back up with a smile.
If you do everything with the intent that it is going to be useful in the long term, your actions and results will immediately have a lot more quality in them. Quick and dirty solutions might work as exceptions… but not as a rule.
