Success is not only a word but also a feeling because of which it's true meaning or definition has not been cleared in the mind of many individuals.Definition of success varies from person to person as some people call it the achievement of desired goals and other call success is nothing but a state of mind.Let me make my words more clear by giving example:A beggar considers himself successful when he gets money by asking,A student considers himself successful when he gets good grades or flying colors,a teacher considers himself successful when he gets positive feed back from his students .It means that success depends on your desire and mind set.You may get success just by putting a little effort like a beggar as his desire is not very much developed he may call himself unsuccessful until or unless he is deprived from his basis necessities but he doesn't do such thing and becomes happy with whatever he gets.On the other hand a student desires something great and put his all efforts in one basket and he doesn't consider himself successful until or unless he become a doctor,an engineer,pilot and artist etc.
So the conclusion is that it's not success that troubles us throughout our lives basically it's our mindset that trouble us.As we can live a happy life with a less expenditure,less salary and less worries but people usually choose life with more expenditure ,more salary and more worries .
