Anxious to move on!

So just the past few weeks I've been so itchy to quit my job and go back to school, or do something different! I've been working part time for Delta as a gate agent for 4 years now and I'm just tired! I worked a full time job at the school district, but in 2005 when I gave birth I quit my full-time job. Before that I was so career driven and I swore up and down that I would be back to work 2 weeks after giving birth, tops! Everyone warned me that once she came it would be a totally different story and it was! So I quit my full time and stayed with my part time (Delta) to be home more with my little angel. It's been about 4 years here at Delta and I look at most of my co-workers and I just can't fathom the thought of being a lifer at Delta! And trust me, there are too many Lifer's at Delta. Although, I'm grateful for it's benefits, traveling back home to Hawaii, leaving for short weekend trips to sunny southern California (where my husband is from), and so on. I am sooooo ready to move on. I just don't feel fulfilled. I've spent money and time for 4 years of college and there's so much more I could be doing. I've been bugging my husband about making a move to Provo and going back to school or even just getting a teaching certificate since I have a bachelor's it would be so easy to do. He loves the flying benefits and can't picture life without them, and so as my dad. I finally told him, "we just need to let go of some things in order to better ourselves." I just feel I'm at a dead end job. All I'm there for is the flight benefits and that's about it. I work as minimum hours as possible and I dread going in the two days a week I actually work. It's just time to move on! I don't see myself at Delta forever! It's just a scary thought to move on, but I know it will be best. We'll see what happens!
