“How can I boost my self-esteem and confidence?”

The first step would be to identify the negative self-statements that you are engaging in and learn to dispute them, replacing them with positive self-affirmations.

Self-esteem if often a head start that our parents give us in early childhood when we learn that we are valuable. Many of us who are cherished don't get that message if we are handed over to someone else. Maybe we are disregarded by busy parents or even parents who weren't cherished themselves and don't have it in them. Some are over regarded and have parents who do everything for them. in any event, self-esteem is an idea handed to us about what we are worth, and somehow we put our self-worth up against others. We are all born divine. There is nothing ever wrong with us, except, perhaps what we learn to think. We are not our idea of ourselves. I was once asked to teach self-esteem in my child's kindergarten class, and I refused. The truth is, true self-worth is earned. However, it requires an ability to express ourselves freely and appropriately. Thus, we need to know how to treat others, so they treat us well in return.
Second, we need to find our niche. Then, take it on. Be curious. Make lots of mistakes trying. Fall down. Get up and try again. Let nothing stop you. Success and regard for others will give you your self-esteem. Learn relationship skills, especially how to give feedback and have a clean disagreement with regard. Expertise and the regard of others (because you regard them) will give you your self-esteem.

Hello. One of the best ways to boost self-esteem and confidence is to identify your positive traits and attributes. When we put our focus on what we do well, it helps to build our internal validation. Creating smaller goals that are attainable will give you more confidence to go onto bigger and more challenging tasks. You are amazing and capable of great things!
