“Whether you think you can or you can’t, you’re right.” – Henry Ford
Life is all about your attitude. If you tell yourself that you’re not good at something, then guess what? You’ve given yourself permission to not try, to not give it an honest effort. You’ve planted the seed of doubt that you are unable to do something, so why give it your all? For if you give it everything you’ve got and somehow don’t succeed, you or others might view it as a failure.
Don’t think like that. First of all, you can do almost anything you want in the world, given enough focused time, money, and dedicated effort. There will be limitations on what you can do, but that is true for everyone. Why would you add self-imposed limitations (by telling yourself that you can’t do something, when it is a real possibility for you) to your real limitations (such as how tall you are). Instead, change your thinking. You can do this. It may be difficult, but this should be expected. If it were easy then everyone would do it. Embrace challenges. Embrace obstacles. Tell yourself that you can do something, develop a specific plan, take regular, focused action, and it will be so.
