I have worked in IT for over 20 years and I genuinely am happy to go into work. In my career I have moved from a technician, to administrator, to engineer, to manager, to director, and now back to a sales engineer. My career path has been very exciting to experience, and now that I have taken a step into a new career as a sales engineer, its even more exciting.
You have to have something you enjoy doing in order to be excited about your work. I really do enjoy IT work. While I do look forward to the weekends, I get up and go into the office every Monday without a single sense of dread or not wanting to be there.
Also, keep in mind that culture is a big factor in job satisfaction. Don't look for the best paying place. Look for the place where a vast majority of people like working for.
