One of the most important skills to learn when you want to change your life  is being assertive. Saying no when you mean no. Not letting people persuade you to do things you don’t want to do, or eat what you don’t want to eat.

Recognise what it is that you want and avoid doing things just because you don’t want to upset someone.

Learning to say no is vitally important. Be selfish because that is the way to look after yourself and when you do that you will begin to eat more healthily and exercise more too.
