In order to turn the mind toward the positive, inner work and training are required. Attitude and thoughts do not change overnight.
Read about this subject, think about its benefits and persuade yourself to try it. The power of thoughts is a mighty power that is always shaping our life. This shaping is usually done subconsciously, but it is possible to make the process a conscious one. Even if the idea seems strange give it a try, as you have nothing to lose, but only to gain. Ignore what others might say or think about you, if they discover that you are changing the way you think.
Always visualize only favorable and beneficial situations. Use positive words in your inner dialogues or when talking with others. Smile a little more, as this helps to think positively. Disregard any feelings of laziness or a desire to quit. If you persevere, you will transform the way your mind thinks.
Once a negative thought enters your mind, you have to be aware of it and endeavor to replace it with a constructive one. The negative thought will try again to enter your mind, and then you have to replace it again with a positive one. It is as if there are two pictures in front of you, and you choose to look at one of them and disregard the other. Persistence will eventually teach your mind to think positively and ignore negative thoughts.
In case you feel any inner resistance when replacing negative thoughts with positive ones, do not give up, but keep looking only at the beneficial, good and happy thoughts in your mind.
It does not matter what your circumstances are at the present moment. Think positively, expect only favorable results and situations, and circumstances will change accordingly. It may take some time for the changes to take place, but eventually they do.
