I don't know about anybody else but when I was 19 I was bursting with wisdom.
I was going to college on a full ride athletic scholarship but I needed some extra spending money. so, I decided to look for a part-time job. Light bulb went off. Aerobics instructor popped in my head. I'll meet a lot of women and it can't be that difficult cause I'm a well conditioned "athlete" tennis player. I applied at a women's gym for an aerobics instructor position, yet I've never even attempted any form of aerobics in my life. The gym owner asked me if they could watch me participate in a high impact aerobics class. I'm like sure. No problem. I knew I was going to impress the hell out of of them. So, we start the class and everything is great for about 2 minutes, then the pain sets in. I'm already out of breath, wondering when the hell this is gonna end. Somehow I make it to 5 minutes. The instructor tells us to relax. I thought, whew, I made it. It was hell but I did it. Yeah!!! Then all of the sudden, the instructor said, 'okay gals, are you warmed up and ready to rock it?" Then they start the high impact part of the aerobics - 3 times as hard as the warm up. After a few minutes, I thought my knees were going to give out. So, as inconspicuously as possible, I excused myself. I completed 8 minutes of the hour long class. I told the owner that I had another "job interview." I swear they could hardly hold back the laughs. Needless to say, I didn't get a call back.
