Want to achieve more self confidence? The best way to do that is to focus on helping or contributing to others. Lack of self confidence is actually conceited in that it is all about you. YOU are not good enough, YOU are not thin enough, YOU are not smart enough or YOU aren't good enough for love.... all focus on YOU. This thinking is self focused rather than self actualized. Self actualization is when you accept who you are and are fulfilling your full potential; or at least working toward it. Self focus is when you solely focus on yourself, you are not trying to grow or evolve rather just thinking about yourself, your needs or what you lack.
If you want to have more self confidence, start to think about what you can do to help others. You could volunteer, mentor a child, help a friend, offer your time and resources, whatever it is... just take the focus off of yourself. Put the focus on lifting others up and your confidence will automatically build. Turn that self "focus" into self actualization and evolve as a person. So if you lack confidence, find local volunteering opportunities, focus on building someone else up while you evolve and Live Inspired Now!
