Surviving is only the beginning. The answer has more to do with the question than with your answer. If change were so easy everyone would be doing it handily. The fact is that change, especially personal change, isn't easy. Just because it isn't easy doesn't mean we can ignore it.
Little changes are tough.
Big changes are tougher. Radical changes are toughest. My advice on changing is simple. Don't plan on making big changes to keep up with your changing environment. Instead, consistently make lots of little changes.
