I won't lie, right now I'm in stage 2/3 of the pipeline and I hate it. But I think that's how it's supposed to be. If it was easy everyone would do it. If you signed the contract to be a NUC you are smart enough to make it through. It will take determination and self motivation to push yourself through. We lost a guy in our class cause he couldn't handle the stress, and he went to the fleet as a conventional ET. Another guy decided it wasn't for him and left too. Of course he had to do more than that to get out of the program, but I won't get into that. Once in the program it's not that easy to get out because your an investment that the Navy has made.
It can be a complete 180 degree change of lifestyle. It was for me at least. Be prepared to not have very much time for yourself, and have to deal with a lot of BS, but i think the whole Navy has a lot of BS to deal with. If you have any questions I'm still at NNPTC in SC till about OCT, so I know the latest and greatest on what the base is like, feel free to ask.
