8. Recognize the good things going on in your life.
And tell others about your positive experiences. People will be drawn to your enthusiasm, which can boost your self-esteem.
9. Don't let envy sidetrack you.
Best friend land a promotion? Got a workout buddy who lost more weight than you? Instead of comparing yourself to others, concentrate on what you want to accomplish. Have you made improvements since last year? Are you taking steps to get to where you want to go? Write down your accomplishments--you may be surprised by how they really stack up.
10. Share your thoughts!
Don't be afraid to speak up if you've got an opinion. The more you stand up for your views, the more others will see you as self-assured--and that translates to feeling better about yourself.
