There will always be people who do not believe in the great and wonderful things you can do. Make sure you are not one of them!
Believe in yourself and give yourself the victory, not defeat.
I was talking to a friend recently who was full of defeat. She had plans to do a bunch of things, go to school, buy a house, get a better job, be a better mother. She was complaining that she was failing in all her efforts and that nothing she touched worked out and that it never would. Her husband tried with all his might to convince her to keep going, to look at things in a positive light, to be encouraged and to stay strong. She just could not let go of the defeat.
My son is sixteen years old. Ever since he could talk he just assumed, inferred, and stated that everyone liked him, everyone was his friend, and he could literally do anything in the world. He never let things like reality and hard times deter him from his belief that life will turn out wonderfully. I admire his optimism. I like the fact that he believes in himself and that God will bless his efforts.
