Destiny is in your hands. Rise up and take it. People with a lot less than you have, have been known to make it.
Determination is key, first off rise from the bed of self pity. Leave your past in the past and Don’t look back.
You’re all you need to be happy and to succeed. Tell yourself that a hundred times a day if need be.
Channel your energies into developing yourself. Are there skills you posses that could stand you out? Develop them.
If you are a Christian or Muslim pray and develop a close relationship with God. Talk to him to show, tell him to show you what to do and how to show what to do and how to go about it. Consult God for every single thing. He really answers.
