For providers here on Eccie, the best advice I could give would be to treat every single client as if he had the potential to become your one and only.
If you put your best foot forward, the word is bound to get out on how incredible you are. The much desired sugar daddy could very easily be someone you're already seeing. Any client just might be "the one" without you even knowing it.
Past dates I've had that were 2+ days in length, started off as 1 hour dates. The one hour requests soon turned into two hour requests, soon we added in social time and going to dinner and bowling and playing pool, shopping, fine dining, meeting in random cities. For me it was something that grew.
