Future Education

I'm thinking of this way far into the future. Maybe 2 or 3 years into the future.
Basically, right now I'm trying to be a Dental Assistant and be certified for things in my state. But, I wanna move to Orengon, where my boyfriend is from. I'll try to also get certified for the things that state says I need.
After all of that and living there for maybe a year, I'd like to go back to school for a while to be a Periodontist. That could take anywhere from 8 to 12 years. I don't want my bf paying for everything and I would still like to work.
I'm not entirely sure that I can work part time and go to school part time while ocassionally being able to spend time with my bf and other friends. (I also have some friends who live in Oregon). The first 4 years of school I can figure out how to make it work. But, going to a Dental School would be a bit difficult.
I know part time is as far as I'll go with working. Hopefully I can figure this out in about 3 years. Maybe I'm just worrying too much. Idk. I just don't wanna drop out of school because I cant work and do school at the same time.
