Happiness doesn't depend on any external conditions, it is governed by our mental attitude.
A positive attitude causes a chain reaction of positive thoughts, events and outcomes. It is a catalyst and it sparks extraordinary results.
The meaning of things lies not in the things themselves, but in our attitude towards them.
So long as you've got your friends about you, and a good positive attitude, you don't really have to care what everyone else thinks.
Ability is what you're capable of doing. Motivation determines what you do. Attitude determines how well you do it.
