What is a good career field for someone who needs to start over?

Hey Odi-

First of all, never let anyone tell you that you're "too old" to get hired. What the heck? 40 isn't old! You are at the perfect age, enough maturity to deal with things that younger employee can not perhaps. In terms of deciding what you want to do - nobody can answer that for you... except you! I'd suggest checking out http://www.careeroverview.com - might help you get some clarity. Hope that helps!
