Have faith in yourself.

In life , there will inevitably be obstacles to encounter .
But don't worry that they will seem too great for you to handle , because you can.
You may doubt yourself at times , but know that if you have faith , you have everything.
Faith is the key to being successful.
If you know you're capable of anything because of who you are , you will always reach your destination.
It may not always be easy, but it will always be worth it.
Look ahead of you , never behind.
Have faith in yourself.
If you do, you will be amazed at what you can accomplish..

We either make ourselves miserable, or we make ourselves strong.  The amount of work is the same.

There's only one corner of the universe you can be certain of improving, and that's your own self.
