You did not choose me but I chose you.
And I appointed you to go and bear fruit, fruit that will last (Jn 15:16).
SEVEN LESSONS FROM A FRUIT TREE
Lesson #2: YOU ARE CALLED TO BEAR YOUR FRUIT!
Do not try to bear some other fruit. 
The second malady that affects one in bearing one's own fruit, is that which is called 'the pleaser phenomenon'. When one wants to bear a fruit, merely because someone wants them to, they are giving into pressure or into the pleasure of pleasing people. A person who does something, however good that action could be, merely at the behest of someone else, has already lost the merits of that action.
Do not think demeaning oneself is a virtue; it is not. Neither would demeaning others be a virtue. Accepting oneself and others as they are, that is the right perspective in life.
Consider John the Baptist who with no feeling of regret announces that he is not the expected Messiah. He neither wanted to bask in a borrowed glory nor did he shy away from the limelight in preparing the way. He bore the fruit that he was to bear and today stands a great icon of having lived his life to the full, having borne a fruit however insignificant, the fruit that he had been appointed to bear.
