The decision making process. By taking this course you are working towards being a strong critical thinker and decision maker. By consciously investing just a little time to review each decision you make, you will continually strengthen your decision making. This will help you build your strengths and confidence in future decision making and broaden your ability to make more and more excellent decisions. The chart here shows the decision making process. First, experience and book knowledge coupled with common sense leads to wisdom, wisdom leads to better and more confident decisions.
Better and more confident decisions lead to more fun and a better existence in general. Then the cycle starts all over again for even better decisions. This is a never ending process and improves with diligence and purpose or fades away with non use. One final point don't beat yourself up if you make a bad design. We all do. Everybody does, no matter how good he or she is, it's part of being a human being.
Just brush yourself off, get up and move on and learn from these. I suggest instead of calling them mistakes, we call them learning opportunities.
