To think that just because you have achieved certain things in the past that you can continue to achieve them long into the future is wishful thinking. It takes more effort to maintain the same reults. And also, you would be required to learn new things so you can produce the same or better results in the future.

Don't entertain the idea that just because you were able to get stuff done in the past that you will continue to perform at a similar level. It doesn't work that way. You cannot give yourself the luxury of "coasting" through life.
