Your own beliefs are all that matters
Has anyone ever told you could not be something you were so determined and knew you could be? Did you ever try to do something, and all you got were reasons why you needed to give up, stop trying, or just that you are not good enough? I suppose we all have been told something like this at some point in our lives, especially by the people we thought would support us.
What thoughts did you have after that? Did you let other people’s opinions of you dictate your abilities? Did you take it to heart that your father told you when you were six that you would always be a failure?
It does not matter what anyone, not even your parents, your spouse, your children, or whoever thinks about you. Your thoughts about your abilities and your determination to make it are all that count! As long as you know why you want it, the how will unveil itself when you get started.
