Half empty or half full?

It is better to have good disposition over matters we need to deal each time. And be an optimist using better judgment and sensible ideas to attain favorable result about what's happening around us. Being pessimistic just put us in mire and lead us to more undesirable and perplexing situations. But if we become more optimistic and hopeful, we tend to think better and solve everything in time without being puzzled and confused to earn and learn but nothing.
