Aspire for what you desire, if you misfire never retire but refire. Your desire will be delivered when you less expected.
In life when the going gets tough, the tough gets going. There's always light at the end of the tunnel. Never allow anybody to talk you down when you are doing what is right. When you know what you know, there's no need to entertain what they think. Keep firing to achieve what you desire and never give up or retire until it's delivered.
