Future goal?????

i have a new goal in my life, i decided to go back to university at the age of 38, to do a BSc, i am doing geosciences which is a great challenge but i love it, ive never studied science much before and certainly wasnt allowed to do it much at school. My eventual aim i think is to concentrate on volcanology, especially monitoring of volcano activity, i want to go and work in the US eventually but i will take each step as it comes.
