there is a simple philosophy i teach in a class at an agency i work for. its based on the principal "if i do good, i feel good". one thing to remember is that we have all kinds of thoughts, both positive and negative. our thoughts lead to our behaviors which lead to how we feel about ourselves. so if we are having negative thoughts, this will lead to negative actions which leads to negative feelings about ourselves. since you cant control what type of thoughts you have you want to find a way to flip your negative thoughts to positive thought to motivate yourself to take positve actions so you can feel good. if you hate cleaning your house, you cannot simply say "i love cleaning my house" because that is not a truth and will not motivate you to clean. but you can tell yourself that you enjoy living in a clean home and focus on that thought to motivate you to clean and the outcome will leave you feeling happy and calm in a clean home.

so you can apply this principal to all areas of your life. Make healthier choice in your diet and exercise. When you take care of the things you love, your treasures, things that make you happy, you feel better and your self concept increases. Our self concept is something that constantly changes. When we are feeling good about our choices it increases, feeling bad, it decreases. So we want to continue to make good choices so that it stays high. Figure out things that you are good at. Hobbies, talents. Stay involved in those things because when you are doing them you will increase your self concept. Treat others how you want to be treated, with love, respect and kindness. this will increase your self concept. Being honest with yourself and others will increase your self concept. Setting goals, they need to be reasonable, measurable. working towards goals and being successful, no matter how small will increase your self concept.

so again, the idea is to do good to feel good.
