I find your comment about establishing boundaries and curating a select clientele interesting. Are you saying that when a SP business is in start up mode the SPs are more likely to offer a more extensive menu of options, some of them including activities that they do not especially like and which they later make unavailable. I ask because I've wondered why as time goes by sometimes some activities can become restricted or limited.
When we start out and start building, often our inexperience is guided by the clients we meet. Especially when we don't know others in the field, and all you have to go by is assumption, and learning on the go.
Often we feel pressured into offering things we aren't comfortable with, until we learn what boundaries we need, to make it a sustainable revenue. A job you hate doing, you don't want to be available for.
The way to maintain momentum is knowing your limits, and forming the environment you are able to maintain/sustain to keep going.
As time passes, and you develop a clientele that fits your preferences, you don't need to be available to see just anyone who wants to indulge in the things you don't want to participate in.
We each develop our own expieriences, and things we offer. We are more than just looking pretty to have fun with. We are all types of personalities, and expieriences, beyond the physical acts alone.
