I realized this late. Its better to get out of the tensions in life as early as possible. When something is bothering you a lot, try to complete it as early as possible.
For example if some person is not coping well with you or you feel you are not able to maintain a good relation with a group then its better to leave that group and move ahead.
Life is not enough to live with some bad things or thoughts. You must move ahead of things which disturb you a lot.
