is your goal realistic?

ANY goal is realistic.  The question is if the time frame you give yourself is realistic.  We as humans never fully realize our genetic potential.  If I wanted to take my guitar skills to the professional level, that would not be an unrealistic goal.  But if I said get to that level within less than a year, that would be unrealistic, but the point remains that I have the potential to get there.  If we believe it to be possible and likely, we are more likely to work hard to get there.
