It happens when we are on same levels with same strength and carry same attitude toward our goals, we become jealous. Such that we want to keep others shut and to refrain from our way; we don’t wish anyone to obstruct our path. It seems good when we deserve single-hand victory, however, real world will never let you to get a single-hand victory; it never exist.
Thus, Be co-operative and start with sharing ideas with those who deserve equal or more than You. You will be served better, just believe. 🙂
