Can I be strong willed enough......

Well per my sisters and husbands request I have contacted schools to study criminal justice. I don't want to be a cop but I wouldn't mind being a probation officer or juvenile probation officer or something like that. Can I be strong willed enough to actually finish this. My patience tends to get the best of me at times. Maybe I am finally tired enough of my life that I realize I need to do something with it besides settling for less than acceptable. My husband works hard why can't I? I made it through basic training I can do this. I just hope I can get financial aid or I'm screwed. But the school does have scholarships for military and I got my G.I. bill. So lets all hope and pray that I can do this and finish. I will need the support of my family and when I am down and ready to give up I will need encouragement alot of it. If I do decide to go to this school I will let people know when I do. Wish me luck. Everybody have a beautiful day!!
