Focus on yourself and do not worry about what other people are going to think.

People will always base their opinions on what worked for them. Don't follow the choices of other people if they don't work for you.

The past does not have to be an obstacle in your life. 

Recognize the undesirable ways your past is affecting your present behavior. Teach yourself to act differently and to think about the kind of person you want to be.

Fear will hold you back from reaching your dreams.

Don't be afraid to make mistakes. The only way you will ever know if you made the right choice is by simply making a decision, to begin with.

Let your loved ones know what you are trying to accomplish. They can influence and help you when they know why and how you are changing your life for the better.

Identify what you want to change about your life. It can help you focus on the promises you're making to yourself. 

Try to focus on one change at a time.

Try to think about the experiences that truly make you happy and engage with them as often as you can until they are wired into your brain.
