"Every positive change in your life begins with a clear unequivocal decision that you are going to either do something or stop doing something"- Brain Tracy
Life lived with a purpose is a life lived with something discovered, done and done well. To live and find nothing doing is to be merely existing and breathing.
No one was sent to earth without a seed. What you may be is "fruitless". But the fruitlessness of a person does not mean he has no seeds.
The question is have you discovered something to do and be remembered for? Have you been doing something that will give comfort to another human being? Can someone testify of your productiveness on earth?
Decide on something worthy to do. Put a stop to all fears and intimidation from the crowd. Let your decisions be transparent, equivocal and clearly outline.
Having done that, prepare and go to work on them, changing the entire world, but beginning from you!
