One can think positive when everything is going well. It is when things are not going well, you need to be in the right mental state. After all, with the power of your thoughts, you can 'wish' almost anything to happen. So with the power of your thoughts, you can fix anything. Correcting our thinking is the surefire way to correct our life and then see how you move on in life. I do the same thing with people. I look for something positive in every person I am familiar with, either their qualities or some events and whenever I meet or think about them, I keep these as my foremost thoughts. No wonder, I have always attracted such wonderful people into my life!!!
