*Smiles and offers a cup of tea* Well, I think you are probably getting the 'almost graduated' jitters. But, you know what? You don't have to limit yourself! You really don't. You'll love childcare, but most childcare people get burned out pretty quickly if they don't have other things to do when they get home from work. My suggestion is (between now and the time you get to travel, when I will expect a visit from you, no excuses) to try to think up some things you really like doing, or better yet, some things you'd like to do but haven't tried yet for whatever reason. Incorporate that within your lifestyle. Kids are wonderful. I love them with all my heart, but you have to remember to keep a space for you or you will become unhappy.
Don't worry. Choosing to follow a career path doesn't damn you to that career if you get restless down the road! Schools are always there and grants are there in oodles. *Big squeeze* I'm proud of you!
