How to Be Confident?

Do Things You're Good At
What happens when you do things that you are good at? Your self-confidence starts to soar. Your strengths become even stronger, which helps improve your belief in yourself. Taking this approach also has another benefit: it can increase how satisfied you are with your life.
One study found that believing in your ability to build on your personal strengths is moderately related to life satisfaction levels.14 This starts with identifying what those strengths are. Then, work to make them stronger by engaging with them regularly.
If you're good at a certain sport, for instance, make it a point to train or play at least once a week. If you're good at a particular task at work, try to do that task more often. Building on your strengths can also help you build your self-confidence.
Know When to Say No
While doing things you're good at can give your self-confidence a boost, it's equally important to recognize situations that can cause your confidence to plummet. Maybe you find that every time you participate in a certain activity, you feel worse about yourself instead of better.
Saying no to activities that tend to zap your self-confidence is okay. Certainly, you don't want to avoid doing anything that makes you feel uncomfortable because discomfort is often part of the personal growth process. At the same time, there's nothing wrong with knowing your boundaries and sticking to them.
Setting social and emotional boundaries enables you to feel safer psychologically. It can also help you feel more in control. Self-confidence is, in part, feeling like you have control over your life.15 Boundaries help establish this feeling of control.
The next time someone suggests doing something that you know will lower your self-confidence, respectfully decline. You don't have to avoid that activity forever either. Once you learn how to be more confident, you may feel strong enough to try it again—without hurting the confidence you have in yourself.
