#1 - Know what you are doing.
#2 - If you do not know what you are doing, ask
#3 - If that is too hard, sell your bike
#4 - Plan and research a lot so you have a clue on what to do, what you want to do, what you can do, what you can afford, what you can't afford, what to be careful of, what to stay away from (OBB), and blah blah blah.
You get the picture.
Edit: Oh, improve on SearchFu skills!!
