5. Fake it till you make it

There will always be challenges. But focusing solely on a problem is a self-defeating practice. Instead, acknowledge that problems will arise, and when they do, focus on finding solutions as a strong leader. The more problems you overcome, the more confidence you'll build and the easier it will be to find solutions.

In almost every case, when you compare yourself with someone else, it takes the form of negative self-talk about how you're not good enough. Doing this weakens self-confidence. The only person you need to compare yourself with is the version of yourself that you want to become.

Body language speaks much louder than words. When you're feeling down on yourself, change your posture: Pull your shoulders back, hold your head high, stand with your feet wide and put your hands in the air like a superhero. Notice how the new stance quickly changes your mood and boosts your confidence.

There is no magic solution that will suddenly make you a more confident person. But when you focus on making consistent and small steps, you can transform yourself from a fixed mindset to a growth mindset.

Fear can be paralyzing. Ignore the voice in your head telling you that you can't do something, and take action anyway. The more you let fear hold you back, the stronger the negative voice will become. It works in the other direction too: The more you take action, the quieter the negative voice will become.

When you look good, you'll feel good. When you feel good, you feel confident. Wear the clothes you want to wear. Invest in how you look and you'll invest in your own success.

Sometimes we spend more time making up for our perceived weaknesses than we do honoring our strengths. While I certainly agree with improving weaknesses, you might find that your confidence will increase when you play up your strengths. For example, if you're not good at math (like me), don't be a CFO. Stick with your strengths.

Success is part preparation and part opportunity. Study, practice, and do what it takes to prepare yourself for when the right opportunity knocks on your door. If you're prepared, you are more likely to have the confidence to capitalize on the opportunity.

Negative self-talk and pessimism are a vicious cycle, and a drain on your confidence. Focus on your positive attributes instead of perceived weaknesses; focus on your accomplishments rather than on your perceived failures. Keep focused on what is working instead of what is not working.

What is your purpose in work and in life? Once you identify your "why” you'll be more confident because you'll be coming from a place of purpose.
