The main thing that stops us from succeeding is the belief that we cannot. We cannot handle it, we cannot deal, we cannot learn. Whatever it is, we cannot. But humans are so inventive and capable. We can do so much. We can overcome so much. Believe that you can, not that you cannot.
Think about all those thoughts that you have that stop you, that inform your life in a negative way. The belief that you can will carry you further than anything else. Trust that you can.
So, face each day with joy and excitement. Because of what you will face today, you will become a better human. You will become closer to the best that you can be. What an exciting thought! And enjoy the journey!
