It may be time to face some facts in your job search. Look at the fall outage scheduled Bartlett. Is getting smaller and smaller every year. With many like you trying to get in, the competition is fierce. In many cases you are competing with people much older with many years of experience. There is some truth to the saying is not what you know it's who you know. You mentioned your age as 21, so you don't have a lot of work history. I will tell you what the travelers' job is like.
You work maybe two outages in the spring and fall. They are timed to allow the least disruption to the grid. Unfortunately, it's also the same time most schools are offering classes. Say if you get into a job, and you feel it pay well, it may be a trap. If you have a relationship and are starting to have a family, is it fair to them to be gone so much? I waited until my youngest child was an adult before I came on the road 10 years ago. I'm on the road now as I write this still hurts to be away from the family. Luckily, I am close to retirement and have a way out. You are looking at possibly 45 years on the road. Have you not considered the Navy to get to training? That's where I got my experience from.
If family and home are not a consideration, then go for the road and do so with eyes wide open about what you're getting into. Money isn't everything.
