Some people are afraid of changes,or may be they take time to adjust with the changes. They live in their comfort zone. Just like one of the character of "Who moved my cheese?". While avoiding the changes in life they don't see the future zone of comfort they can make. As rightly said in Sarkar Raj,Change is necessary for success. I believe that proper change with enough risk and clear vision is necessary for guaranteed success. Consequences can never be predicted,the only thing they end up giving is experience in making decisions,rather correct decisions. Decisions in any field are either taken under influence (by those people who don't want to take responsibility for the failure) or by instincts (by those who are ready to take any challenge,those who are confident to fight the failure,those who takes calculative risk as a step towards their goals). Correct decision at the right time is the recipe of success!!
This is all true up to some point. When the experience level reaches its peak,the desire of making changes decreases. Its like a self limiting disease. It becomes difficult to differentiate between your own wisdom and your ability to grow. Changes brings growth and rest is Comfortably Numb!!
I think i fall into this category of people. I need to change for the sake of my comforts!
