That's not a dumb statement, that's the truth.Just be aware that training to be a spark as a "mature" student, then getting a job could be an uphill battle.
Re-training and going self employed could be very difficult and it may take 3-4 years to build up a client base and then earn a reasonable income..
You are employed, with holiday and sickness pay and I suspect a decent pension ..... take all this into account........
