Hi Sam,
I'm a firm believer in "it's never too late to start over".
God knows I've done so many times myself.
I would encourage anyone who wants to try something new to go for it.
However, some of the things offered in schools only make the schools rich.
Every student sitting beside you is your competition. If the niche is already crowded, the sheer number of competitors makes your chance of employment go down. Employment is the goal, am I correct?

If you want to work...find a need and fill it.
It's a simple philosophy. If the need already exists...the job is already open!
