Often we talk about rich and poor people, wise and fool and so on. Often these words are associate with financial wealth or the outcome of decisions (wise or foolish).
I like to use these words in different context: your thinking process, the way you think, the way you see life, the way you make decisions, among others. How do we know if our thinking process is the right one? Simple, out thinking process is based on your life beliefs, values, our rules and our defining moments in life.
You can to change your beliefs, so you can also change your thinking process. Remember, life is a constant change. Embrace change and make it part of your life. Live life to the full!
