I am currently working as a Medical istant who wants to enroll at a LVN program. Any advice?

My long term goal is to work as a LVN then after two years continue to RN. I have thought about it for a year now and all this thinking got me stuck for not enrolling yet. Should I go for the Rn right away? Is there any LVN's here who can tell me how they like their job. Anyone who went to Mission College at Santa Clara, CA?
