Learn not to start looking at what people say to you or what they did to you, let your mind be fix on your goal and your purpose in life. Whether you like it or not people who will sing your praises and tomorrow they are no more.
The fact that people join you doing same course in life, same goal, and same job doesn’t mean you people are going same destination or direction in life.
Don’t feel offended when people come into your life and they leave, don’t stop half way to your destination because you are still looking and thinking of those that has left you on the way.
Do not hold on to some one that is meant to be there all the time for you ever if they leave forgive them and let them go because you are still going higher to your own level.
