It is better to look ahead and prepare

than to look back and regret.

Always look on the optimistic side of life,

but be realistic enough to know that 

life is a complex matter.

The man who is a pessimist before 48 

knows too much; 

If he is an optimist after 48, 

he knows too little

An optimist sees the glass half full, 
while a pessimist sees the glass half empty.

Few things in the world are more powerful than a positive push, a lovely smile, a word of optimsm and hope.

Optimism is the one quality more associated with success & happiness than any other
