I've been doing instructional design for a very, very long time. I honestly have 25 years of experience in my field. I'm concerned that if I include that number of years when I apply for a freelance job, potential employers will automatically think that I'm too old or out of touch.
It's not like I haven't kept up with new technologies - because I have. I love to learn, and I love to read, and I'm always trying new techniques.
So, how should I deal with my experience when applying for work? Do I give the actual number, or keep it vague, such as "over 10 years" or "over 15 years?" Or is 15 even too much?
