Considering: cities you will/might visit, clients who had a great time and will come back, guys with issues, teasers, no-shows, guys who text your ass off, sexually explicit callers, etc...
How many have you considered worth saving?
Yet your diagnose was accurate. Good luck to you @Wolfer get treatment or the ups and downs will be more intense. I know because of a friend's daughter, she's doing great now yet she got help at the right time.
You didn't advertise in a magazine or Rentboy? Not sure when exactly I've heard about it but the Blade was enough for me.
did you own a cellphone toward the end of your career.
One more thing I forgot to mention, cellphones weren't good for texting, or at least some didn't have that choice. I remember prepaid phones that till 2002 didn't include voice mail unless you pay extra for it.
@bnm73 Since have changed a lot since the early 90's yet haven't changed much @Benjamin_Nicholas since 2004.
Advertisement in the late 1990's on the internet wasn't the only way to find a guy and local papers or magazines: Bay Area Report, Washington Blade, were very common. Let's remember that Rentboy started in 1996 or 98 yet it had to compete with the printed ads till at least 2005ish. Cellphones weren't as common as now, some of them would charge extra if you were out of town (roaming) and they were also very expensive because instead of monthly payment the prepaid ones charged by minute.
