@Jake Thomas  good points.. when I first started in real estate sales circa 1975.. there was no internet heck there was not even a MLS or a computer on your desk top.. the MLS was a big book.I worked every weekend both days 50 weeks a year.. and I worked 3 to 4 nights during the night.what I did have time though during the day ( because not bogged down on computer or cell phone) was to golf fish other actives that I could do middle of the day..
