I was a secretary/administrative assistant for years and absolutely hated it. I was very good at it, and I have the performance appraisals to back me up.
For me, the work was a no-brainer. It required very little creative thinking. I was bored out of my mind within a year. I guess it just wasn't a good fit. I felt like a slave--always at the beck and call of someone.
If you can put up with filling out the same forms, typing the same letters and reports, attending the same meetings, transcribing the same notes, filing the same papers, answering the same questions over and over again, day after day, week after week, then I'd say being a secretary is for you.
The happiest day of my life was the day I decided I would no longer be a secretary! I wouldn't go back, even for $100,000 a year!
