How to boost your self esteem: Express yourself
Don’t be afraid of being yourself in front of others. One of the main consequences of low self-esteem is that people fear showing themselves as they are. They think that if they do, they will be rejected by those who think or are different.
Learn to express yourself. Your ideas, opinions, your tastes, your preferences. Learn to say “no” so you can say “yes” to what you really want. You can’t always please others.
