Lastly, stop comparing yourself to others—it is a disillusioning comparison and a bad habit. There is only one of you, so be the best you can and start to support yourself more, like you would for a friend. Surround yourself with people who make you feel good, who don’t put you down or make you feel less worthy, but rather those who hold you up and champion you on.
It doesn’t matter what career you are in; having confidence in yourself is necessary to be happy and achieve better results. The biggest difference between those who climb the corporate ladder and those who stay at the bottom is having high self-confidence. Working towards building your self-confidence now is a lot easier than living with the results of low self-confidence later.
