Here's other quotes and sayings you can motivate yourself with. Practice only makes for improvement.

The only limits to the possibilities in your life tomorrow are the buts you use today.

You can start over again! Don't even think about quitting now! It is easy to replay in your mind how things did not work, how much you lost, what you are going through, how angry you are. There is no amount of conversation or magic that is going to wipe the slate clean. You are wasting valuable time and energy that could be used to regain a new normal and start another version of your life. Even though you are hurt and you may be feeling down — stop kicking yourself! Face what has happened. Make the decision to start over again.

No one gets out of the game of life alive. You either die in the bleachers, or on the field. So, you might as well play out on the field, and go for it.

Do what is easy and your life will be hard. Do what is hard and your life will become easy.

Give yourself a break. Stop beating yourself up! Everyone makes mistakes, has setbacks and failures. You don't come with a book on how to get it right all the time. You will fail sometimes, not because you planned to, but simply because you're human. Failure is a part of creating a great life. Stand up to it and handle it with grace. Because, you can.

Never let someone’s opinion become your reality. Never sacrifice who you are because someone else has a problem with it. Love who you are inside and out.
