Don’t let anyone else tell you how far you can go or what you can accomplish, only you can decide where you will go and what you will accomplish. You are your own limit and only you know your own potential.
No matter what you are doing you in life, others will try to tell you what you can and can’t do. They will try to put restrictions on you and tell you that something is too hard or too difficult for you. When this happens you will have two choices, either give up and forget it or step up and prove them wrong.
Here’s the thing, only you can decide what your limits are. If you want something enough then work for it. Get up and prove them all wrong. You set your own limits. Yogi Berra once said that “baseball is 90% mental, the other half is physical.” I would have to agree with him, but I would say that this applies to everything that you do in life. I believe that 90% of what you do comes down to how you perceive something mentally and how much you want to accomplish it.
Do today what others won’t, so that tomorrow you can do what others can’t. The more you work towards your goal the easier things will become. Keep working and keep pushing and your goals no matter how “impossible” others say they are shall become attainable.
