TRUST YOUR GUT! ;)
I have a rule in business & life: if I ask twice whether to do something, I already know the answer. I have enough faith and understanding in myself (as well as the ability to research and make educated decisions) that by the time I need to make a decision, if I keep asking repeatedly "should I do/don't do this", I already know the answer. It is the opposite of what I keep asking. My personal rule is, if I've asked twice, don't do it!
