Life has a purpose, all of us have some purpose in life. Many of us realize our purpose a bit late and a few realize it earlier. When we start working towards our goal we cross many stages, we meet many people who can be generally classified as friends and enemies. These are the people who help you to achieve your goal and these are also the people who stand as an obstacle in your way towards success.
In short life can be treated as a game where u have a mission that you are supposed to complete at any cost. This is a game where many fail and only the best prevail. Be brave and face your problems with courage. Life is too short to be worried about so act quickly and work towards your goal.
