Eat well means to eat little but good.

Eat only when you are hungry. If you eat when you are bored or depressed, get yourself busy. Find something that you like doing so it won't be difficult to do.

Eat in small quantities; you don't need to be full, just not hungry.

Most of your diet should consist of fresh fruits, vegetables, lean meat, fish, eggs, seeds and nuts.

Exercise.

Find exercise you like, it will be easier to stay with it. 

Walk more, drive less, park far.

Respect your body, pay attention to the symptoms.

        Maintain positive attitude. 

Focus on today. Yesterday is gone, and there is nothing you can do about it. Tomorrow is not here yet, and you never know what it will bring. Allow yourself to be surprised. 

Accept things you can't change or influence. Focus on changing the ones that are up to you.

Remember yourself as a child, not the times you were hurt, but the times you were happy. Try to remember what made you happy, what kind of person were you, what were your dreams. 

Find the things you like to do, things you are very good at doing. Do these things on regular basis. Make a decision to become the best you can be doing these things.

Don't perceive yourself as a failure, but as someone that can succeed if you set your mind on it. Set your mind on it.

There are no failures in life, just stepping stones toward our success.
