How to stop comparing yourself to others?

Firstly its a part of habit. Whether you agree or not, its one of your habits. Its a pattern of how you perceive yourself. And this is quite common. I also used to compare myself with others but I was keen to let go of this habit and accept myself.

Whenever you find yourself comparing with others, you need to ask yourself some questions such as

Will it change anything for me?

Am I doing this because I really want to do it or am I feeling envy of anyone?

Do I want recognition from others?

What fears have led me to compare myself with him/her(person you are comparing yourself with)? Is it related to my past or am I anxious about anything?

Is it related to my ego? Do I feel less important in anyone's life?

These questions would make you know the root cause of this practice. You may feel uncomfortable initially, but this is how it works. There are some ways to cope with this situation. 

• Spend time with yourself. 
• Write down everything on a piece of paper.
• Have a positive self-talk or spend time with a friend and tell him/her everything that is in your head.
• Try to meditate.

Although, it won't change overnight, consistent efforts would eventually get you rid of this self-sabotaging trap.

As far as my opinion is concerned, I used to compare because of anxiety. I also had some things stuck in mind which seemed to be gone, but I realized that they still bother me. However their impact has been down.  Sometime people compare you with your siblings or friends or others, and that is something you cannot change because its their opinion. You just need to ignore it as your attention is what empowers you. Or else, if you find it too offending, you can 100% let them know that you are hurt. 

Being competitive is different. It means you are putting efforts to improve yourself and competition is not something that you can relate with personal aspects. Remember that everyone has his/her own destiny. You cannot take anyone's share and neither anyone can take yours. If you are meant to get something, even if that thing is buried under two mountains, it will find its way to you. At any point of your life, someone will be ahead of you and someone behind.  

By comparing things, you are devaluing what you have. Probably, you'll get into overthinking and worry for no reason. It changes nothing and does no good to your life. 

Comparison is a thief of joy. Realizing this would make you appreciate what you have in your bag. After all what change would it bring if you compare Rose with Sunflower?Or do you think that white color would turn black on comparison? The answer is pretty clear, No.
