Keep Moving Ahead

He who is silent is forgotten;
He who does not advance, falls back;
He who stops is overwhelmed;
He who is out distanced is crushed;
He who ceases to grow, becomes smaller;
He who leaves off, gives up.

The moment you decide to stop in life,
its the begining of your end.
Keep moving ahead.
