I have recently left the company that I worked for, for over two years. I felt that I was losing valuble knowledge that I had gained at previous jobs. I felt this way and I know others did as well. Usually you forget things that are obsolete. The problem with our case is we all felt that we were losing things that we should be strengthening not forgetting.

So, here is the real reason that you need to update your resume. It is to keep in check where you have been to where you are going. You need to be able to sit down with your resume and judge if you are where you want to be. If you feel you are truly losing knowledge in things you don’t want to lose, you should move on, don’t hang around ’til it is too late to move on. Make a clean break and move on.
