Doom and gloom
I have to agree with you there is too much doom and gloom about IT.
I wonder what the doom merchants are talking about when they say IT. When I first started in the office, 2005, for a big company some folk classed themselves as IT experts but only worked on one system. Some of them had been on that system for 20 years+. They knew very little about anything else. The system was then switched off and they were fishes out of water. It did not stop me from going into IT all it did was to make me damn sure I was not a one trick pony. I'm still updating my skills and will continue to do so(actually I enjoy being the geek).
As you say and it is a golden rule 'if your not happy F**k Off and get another job'.
