Be interesting, be enthusiastic... and don't talk too much.
Have great hopes and dare to go all out for them. Have great dreams and dare to live them. Have tremendous expectations and believe in them.
Keep your mental and spiritual contact points cleaned so that God can operate through your mind.
If there is no fun in it, something is wrong with all you are doing.
Do not let circumstances defeat you. You can if you think you can.
Don't take tomorrow to bed with you.
