In order to think positively, you have to change your emotional and mental approach toward yourself, other people and situations.
1- Make a decision to do your own thinking and have control over your attitude. That means deciding to conquer the negativity that is going on around you. Think of what you can do today and how you will react that will make a difference to your life instead of allowing people and situations to dictate.
2- Associate or mix around with people who can provide something of value. Avoid those who sap your energy and motivation. If you can't avoid them, or don't want to, learn how not to let them get you down.
3- Start saying positive things especially about yourself. How you communicate to yourself affects your thinking and your emotions, as well as your self-esteem.
4- Try new things. Experiencing a wide variety of life in a positive light will do wonders. Something as simple as trying the mussels in a restaurant can lead to new tastes and different sensations.
5- Read more. Read about how those people who fought fear with courage and succeeded in life. Through reading, you will gain new knowledge and understanding and it will help you clear whatever is blocking your thinking and create more ideas.
6- Set goals no matter how impossible it may seem at the moment. Keep yourself busy working on them. Once you reach one, you will get inspired. With each goals achieved no matter how small, you will gain confidence and your self-esteem will increase.
7- Change your mental pictures. What and how you see yourself and your surroundings make a difference to your thinking. You are visualizing or imagining something at every waking hour. Start to change your old internal dis-empowering pictures with images of something that you wish to experience.
8- Start questioning yourself on your behavior and attitude. Ask yourself why you are resisting or producing the habits or attitudes that you dislike. Stop each time you catch yourself in a circumstance that bring about negativity and doubts.
9- Create your life from within. If you want more success, focus on all the ways that you are already successful. If you want more love, focus on all the people that already care about you and the abundance of love you have to give to others. If you want to create greater health, focus on all the ways that you are healthy, and so on and so forth.
10- Replace negative thoughts with something positive. Look for the good in every situation. There are pros and cons to most situations and you get to choose which you will focus on. If you're thinking something that isn't pleasant, think the opposite. If you do this long enough, it will make a huge difference. Say "I can!" more than "I can't!"
11- Volunteer or help others. Helping others leads to a happier outlook on your own life. You'll feel great at the end and make you feel like a good person.
12- Find an optimistic quote or saying and keep it in your wallet or pocket at all times for a quick reference.
13- Listen to positive music. It's a great way to remain positive.
