Not insane at all, i went to my local Uni open day last year and got a bit of info. I have 3 young children at home at the moment so decided now is not the right time but i sill believe that my time will come. When you think about going back to Uni for another 4 or 5 years (maybe i think....) it's nothing when you look at having another 30 years of work ahead of you. I say it's definately worth your time and effort.

If there is something that you want go out there and get it
