If you are motivated and have a true desire to go to law school I think you should most certainly do so.
A woman that my parents are friends with went to law school after her sons went through law school themselves and had their own law firm. She had an entire career as a school teacher and administrator. I think she was at least 45 when she decided to make the plunge. She then went on to become a judge and sits on the House of Representatives in her home state. I feel she is a great example of the success a non-trad can have in ls.
