Life is mostly about decisions. Should I get some exercise today or stay in bed? Apply for a new job or stay miserable in the one that pays the bills? Date that person or this person? Forgive or not?
I am not the best decision maker because I want everyone to be happy. Happiness is not always possible in good decision making. Sometimes it actually really harms someone else and yet you know its the best thing for all involved. Sometimes you just dont know.
So you look for guidance; from God, friends, past experiences, then you make the best decision you can. Sometimes you regret it, sometimes you wish you had done it sooner.
