Free yourself from the expectations, limiting beliefs, and opinions that others emplace on you. Unshackle your mind from the imprisonment of instant gratification and comfort. Forgive yourself for past mistakes that cripple your present and future.
God believes in you, so should you. Some will tell you why they cannot do something; their excuses have nothing to do with you. YOU CAN DO ANYTHING! 300 lbs. on the couch? Get up and train for a marathon, begin with a 5k.
Lead yourself by demanding more. This will be achieved through a daily regimen of discipline, consistency, patience, and above all grit. When freedom becomes a daily habit, don't hoard it, help to improve the life of another.
