We all get some results, which are the effect of our actions. Our actions are caused by our thoughts and feelings. If we can direct our thoughts and feelings, then we have control over our actions, which lead to the results we get.
The fact is that we have ability to choose thoughts! This is an amazing ability if you look at it carefully. You can choose your thoughts, I can choose my thoughts regardless of what's going on outside!
Many people seem to forget the ability. It's sad!
