Start living it.

Spend your life comparing yourself to others or spend the rest of your life creating the best version of yourself. Choose.

Life isn't getting enough if we keep comparing it with others. Unconsciously, we tend to compare our worst with their best while ignoring the fact that we do have something better than them. This habit will steal happiness and destroyed your contented life automatically. Moreover in this century, where the borderless social media is highly popular, we able to see everyone's life and worse when we conclude that their life is remarkable while we are not. Just to be noted for us, social media is a medium where everything is shown positively, though the worst thing also is presented in a very positive way.  Myself as a social media user, I second that.

Here my humble suggestion. Why don't you create the best version of yourself?
Focus on what you have and do it better! They have an education, but you don't? I believe you know how to bake. Baking better, become the best baker. They work with a big company, but yours is a very small organization? Work harder to make yourself to be the best employee. They are married, but are you still single? Embrace the current relationships that you are in; be the best friend of your friends, the best mate of your colleagues, and the best human in the world!

Looking forward, focus inward.
