I just saw this as a question and it reminded me that I've developed a working system for how I serial date to really unfair levels.
Ok, so I'm going to skip ahead to actually having some people you want to talk to and see/date. How does one keep such a schedule with any consistency?
1) Start slow with only 2 or 3 and go no further than 10
A lot of people want to have a different person for each day of the week. Slow down. It's hard mentally to make the shift from one person only to multiple people at once...yet it can be done even to the most romantic sap. Also if you go too fast you really start to forget who told you what, people's names, etc...
2) Dedicate an hour
It is extremely easy not to have a life outside of texting your people 24/7. I'll send a few texts to keep the conversation going but ultimately I will probably talk to them 5 to 15 minutes a day during an hour i've blocked off where I can call and see what's up. I tend to avoid "checking in" as this is what a cartoon of someone dating multiple people would do. Instead I simply budget multiple relationships and aim for consistency over actual quantity of time. Some might say an hour a day isn't enough but I really value having a life outside of dating...
3) Don't afraid to get nerdy with your organization game. Use a cheat sheet
When I'm in my prime, I have an excel worksheet with the girls I'm talking to another column for girls I consider girlfriends/friends with benefits, another column for my benchwarmer friends with benefits, and out of towners for when i come through a certain city. This sounds like overkill until you start using it and suddenly everything becomes really easy to track and understand even among multiple girls with only minor updates needed when you meet someone new.
4) Always have someone on back up and privelege people who are closer to where you live
The reason for this is if a date goes badly or somethings just not working out or if you have a flake you can call up the next girl or at least a girl who's your ride or die to let you get some if you feel like you need some TLC that night.
5) Pay in cash
This is hard when paying for drinks or dinner as the bartender or waiter has the bad habit of reading the name on the card sometimes. For women too, avoid doing anything that reveals your last name until you're ready to be exclusive with this person as stalking can easily ensure regardless of gender...
6) Think of dating as an ecosystem. Run people through your system
Ideally, you should be having numbers coming in and coming out. Whether you simply found out they weren't your type or got what you wanted out of meeting them its very often people fall off. in fact, in order to date new people you need some people to fall off which is why you can afford to be a little picky.
7) Use your Calendar and contact photos
You can tell siri to schedule the date so you don't forget. Also always have people send you contact pics so you have a mental note for remembering who they are.
8) Have sex with them before becoming exclusive
Temptation for both men and women is to hold off on sex when you REALLY like a person. nothing could be more erroneous. Sex is THE SINGLE BEST way of bonding with someone to you if done right. I'm not saying rush into sex but don't get lovestoned on someone before you've gotten naked with them or you're just asking for trouble.
