Making comparison to others is an unrealistic and unhealthy and that in turn leads to bitterness, jealousy, frustration and stress. Some people always keep themselves engage in comparing their personality and possessions to others. They keep their focus on other persons personality and possession. They simply do not understand that comparison has no limit. It does not matter at whatsoever position they may reach in their lives, there will be always a person who will be above them and there will be always a person who will be below them.
The habit of comparing yourself to others will lead you to remain stressful throughout life. You will be always on your toes to outdo others. It may not be realistic about you to achieve what someone else has achieved in their life. Different people have different experiences and perspective, and they face the different situations and circumstances in their life to be where they are.
The best way to avoid making comparison is by being yourselves and deriving maximum satisfaction with whatever personality and possessions you are having. And by being engaged in the process of achieving whatever makes you happy. Realize that you are unique in your own way, and you have to set and achieve the goal in harmony with your own true potential. And always remember, you cannot live a life of another person so do not make a comparison to them.
