<prompt> Human: So I am 27 right now. I work for a Fortune 200 company and I feel like I am working a dead end job. I have made one job change at 23, and I have been with the current company for 5 years... I am curious what other people opinions are on changing jobs or what I should do?EDITA little background on me:27M - BS in Civil EngineeringWorking on getting my MS in Engineering Science with a concentration in sustainability and energy engineeringThe current company I work for treats me well I am top 3 in my group. But my issue is in my head I am freaking out because I think I will be doing the same thing just different designs over and over again for my whole career.  <response>: From the time I was 15 to 30 I probably held 9 jobs including owning my own businesses. I have been with my current company for 3 years and will probably be there for another 3 while I complete schooling. I just now decided to go back to schoolThis is not the old days where you stay with one company. Let me tell you what my 85 year old cousin told me:He said that if you start at a company in the mail room and move up a couple of slots you will still always be that kid from the mailroom and they might think you should be content with what you have. You have to at some point latteral over to another company so you can start on a higher ground floor. I have found this to be true.
