To simplify, you need the right mind set. You have to think throughly and carefully why you are doing what you are doing. When you know the answer to why you are doing certain things, you will be able to determine if what you are doing is really necessary and also analyse whether the way you are doing it is the correct way to do it.
That actually means simplification process is not all that easy to achieve. It is also a continuous learning process.
