Benefits of being self-confident
It just feels good to be confident in yourself. However, having self-confidence can provide numerous additional benefits at home, at work, and in your relationships. Here are a few of the advantages of learning how to be confident:
Better relationships: Self-confidence affects not only how you feel about yourself, but it also helps you understand and love others. It also gives you the courage to leave a relationship if you aren't getting what you want or deserve.
Openness to new experiences: When you have faith in yourself, you are more willing to try new things. Putting yourself out there, whether for a promotion or a cooking class, is much easier when you believe in yourself and your abilities.
Better performance: Instead of wasting time and energy worrying about not being good enough, you can focus your efforts. Finally, having more self-confidence will help you perform better.
Resilience: Believing in yourself can also improve your resilience, or ability to recover from any challenges or adversities you face in life.
