There is one type of illness in the world that affects more people than anything else and is very deadly. If untreated this illness could affect everything you do. What is this illness? Depression. Serious depression requires professional treatment. Self-induced depression is something each of us can change.

Everyone's circumstances are different, but the causes of self-induced depression are common: low self-esteem, hurtful thinking and a bad attitude.

So how can we change the way we think, feel, and cultivate a cheerful attitude?

First we must look at ourselves, truly and honestly examining our motives for what we wish to achieve. If you are dissatisfied because you feel you haven't or can't do anything, then one step is needed - to set goals.

Always start your goals relatively small and easy to attain. Think of them as sand; one grain may be insignificant but as a group they form the beach. Once you have set and attained small goals for yourself, move on to slightly larger, more challenging goals.

It takes more than just setting goals to be happy. It takes positive thinking. How can we attain this?

There are a number of factors that can make us think negatively and one of those is diet.

In my opinion, a person who eats a lot of take out and fast food is feeding their body junk. Start by eating better foods which give the body much NEEDED minerals. If your physical body is happy, it's much easier for your mental body or "thinking ability" to be happy.

Next, exercise. A half-hour a day is recommended for positive well being. Then think about good memories you had, or generally think of things that make you smile. Remember, everything you wear costs money but to wear a smile is free. A smile can be the difference between an average day and a great day.

If you follow these steps, positive change is inevitable.

Positive thinkers admit when they feel frustrated or depressed, they don't ignore it. But they don't blame themselves either. Instead, they try to understand the negative thoughts and feelings and counter(反击) them with more positive ones. So how do you stay positive, maintain motivated and sustain healthy behaviors? Here are some tips:　

Look for a good role model. There is always someone who seems to be doing just what you want to be doing. Maybe they've scheduled exercise into their workday and switched from coffee to green tea. Learn from a successful friend, family member or colleague. Ask them how they keep healthy and follow in their footsteps.

Try some positive self-talk and avoid negative-talk. Take a minute to give yourself an ego boost. Repeat some motivational words out loud to yourself. Negative talk such as "I can't do it," "I'm fat," is dangerous for your well-being and healthy goals. Try to avoid the negative self-talk before it harms you. Remind yourself that you deserve happiness and can make positive changes.

Get support. Tell your friends and family about your healthy habits. It helps to have an encouraging network.

Reward yourself. Treat yourself to something for your healthy efforts. Take a nice bath, get a massage, and enjoy a new DVD or CD.

Have a plan. Making a plan to exercise or eat healthy lunches with a friend can mean the difference of sticking with your goals or falling off track. If you've planned for an activity, you'll likely stick with it. You may even find that writing down your goals and steps to achieve them can help you stay on track. Take it day by day or week by week. The process of writing down your personal action plan is a good way to keep you honest and watch your progress or failures.
