Would You Be Successful?

How often do you attempt something new, and within a few days or weeks, you quit?  Abviously you saw potential, some opportunity, and you went at it with such verocity and excitement only to throw in the towel.  Why is that?  For many it is the constant pressure, or negative talk from those closest to you.  We value their opinions, and we feel that they know us the best.  Do you agree?  I feel that other people see things in me that I do not see, but in no way do I think that other people know me better than myself.  So why do we listen to other people?  Did we seek their advice, or is it just thrust upon us?  What if you did not listen to other people the next time that you felt that excitement of exploring a new venture?  Would you be successful?
