Perception is necessary for progression. When you have the wrong perception about life generally then you are bound to keep making mistakes. Mistake is not bad in itself especially when you learn the needed lessons and forge a course to move ahead but it becomes a problem when you do not deal with the source of the problem and as a result your life becomes a whole mess. Our mindset is a very important part of this process. If your mind is not set right, you will never develop the right attitude towards success.
