There are things I will never be able to do. There are also things I have done that I never thought I would be able to do. There is one lesson I have learned over the years related to this. If I say I can't do something I have just guaranteed myself I never will. I have accepted it. I have given myself permission to not even try. But mindset can be a powerful thing. Over the years my wife has always stopped me many times when I would say I can't do something. She will say, sure you can. You just need to try. When we say I can't, we usually mean I don't want to try. And we are giving ourselves an out. We are making an excuse for not trying. I once heard Jack Spirko say, "Don't say I can't. Say how can I." It is easy to make excuses but it is rewarding to find a way.
Stop saying I can't. Start saying how can I. Sure, there are things that are impossible but most things we just give up on before we even try. Don't kid yourself. If you just don't want to do something then don't do it. Be honest. That's OK. Maybe you don't want to spend the time each day to learn an instrument. Maybe you don't want to work nights and weekends to prepare yourself for a new career path. But don't kid yourself. We are capable of far more than we believe. It starts in our head and with what we tell ourselves. Start thinking, how can do what I want to do?
Hope this helps someone.
