Your Self-Esteem depends on how you compare yourself to other people both at work and in your private life.
If you are forever comparing yourself with the amount of money that other people have, or comparing the size of your house with the largest house in your area, or comparing the clothes you wear with a super-model’s, or comparing the size of your chest with a weight lifter’s, you are going to have low self-esteem.
But if you don’t play the “compare” game and just accept that at the important levels of humanity everyone is equal you will find that you become a great deal happier in your life.
Certainly everyone has different skills and abilities, but that is because we are all unique, so there is no value in comparing your skills and abilities with those of other people.
Self-esteem is about the value that you bring to the world. Your value will not be the same as other people’s, but it will be what you add, and that will always have value somewhere, in some way. You are special, you are wanted, you are talented and you are valuable.
