Someone's opinion of you does not have to become your reality.
When you are not pursuing your goal, you are literally committing spiritual suicide.
Review your goals twice every day in order to be focused on achieving them.
If you want to be rich watch what rich people do everyday and do it. And watch what poor people do and don't do it.
Accept the consequences of your actions in order to become the agent of your mental, physical, spiritual and material success.
Don't underestimate yourself. You are capable of more than you can ever imagine.
