WHO TOLD YOU IT COULDN’T BE DONE, AND WHAT GREAT ACHIEVEMENTS HAS HE PERFORMED THAT QUALIFIED HIM TO SET UP LIMITATIONS FOR YOU?
You will find as you go through life that those who give advice most freely are precisely the individuals who are least qualified to do so. Busy, successful people don’t have an interest in telling you how to live your life. They are busy living their own. Failures or mediocre people have all the time in the world. They also delight in seeing you fail, and are quick to say "I told you so" when you experience a temporary setback. If someone tells you that what you are attempting to achieve is impossible or not worth the effort, take a close look at them and what they have accomplished with their lives. The chances are good that you will find they haven’t done much. Successful people are optimistic people. They have the habit of success because they learned long ago to listen to themselves and not to those who would like to see them fail.
