I started school a little after I graduated, and in hindsight, I wish I could have started right after. I was afraid of college, but I'm not afraid anymore. It's a rewarding and very motivating experience that I would never take away from myself. So, in other words, don't be afraid of the change that comes with attending college. Typically, that change is for the good.
I wish that I had known that I had the ability to balance work, family, and school. I also wish that I had one clear focus of a major.
The distance is a major factor for me. I wish that I knew how far the comute was both from work and home.
