To believe in yourself, you must believe that you have the qualities or skills you need to do whatever it is you want to do. So how does that work? Well, to start, it can be really helpful to create a list of your positive qualities and strengths. That way you'll know what they are.

Next, think about how these positive qualities and strengths can help you reach your goals. 

And if it turns out that you're missing key strengths that you need to reach your goals, then start working on building those strengths. None of us come into this world having everything we need to accomplish everything we want. So if there are still skills you need to build, focus on how your existing qualities and strengths can help you build those skills. We grow a little at a time, believing in ourselves a little more with each successful step we take forward.
