How can a person who has been unemployed for some time keep their morale up?

If it's been so long that you're thinking you won't find work in your previous area, then re-train! I've done it three times in my career and am about to do it again. You have to be versatile, especially in this horrible economic environment. Talk to a counsellor at tech/TAFE (whatever they call it where you live) to find out what are your strengths, and what areas you might work in that still have staff shortages. You could even find that courses are free (some are in Australia if you're unemployed). Keep your chin up, stay positive always and good luck!
