Congrats on wanting a career change!
I've been a technical manager for over 5yrs and have been in this industry for a long time, although Im younger then you
A few things I would suggest:
1) Definitely complete your AS, especially since you are so close to finishing.
2) Check with the CC's career department. Alot of CC's are tightly integrated with local businesses that are looking to hire recent grads. They can sometimes point you to local companies that are hiring and give you a heads up on what theyare looking for.
When you say computer related, specifically what you mean?
Is there something particular that you enjoy?
Also your age has nothing to do with you being hired or not-hired. It's illegal to base a decision on age. If you ever supect that is the case, I would promptly file a complaint with the EOC.
