NOT CRAZY!!
Its very interesting your saying that because not too long ago I was really inspired by my great great aunt (kh- may she be healthy! Shes in her high 80’s and is GOING BACK 2 SCHOOL!!! FOR REAL!!!
So, for goin back at 30 is not bad @ all its pretty awesome!!
As long as you have your prioties set, and you manage to juggle both life and college without affecting the people around you- then KOl Hakavod- Im cheering you on!! Go for it!!
And GOOD LUCK!!!
