I know this personal trainer who swears by this philosophy: if you hate something, DO IT. And do a LOT of it. In the realm of fitness, this translates to burpees for me. UGH!! I seriously don't like these. So, you know, that trainer suggested that I do a TON OF BURPEES.
Her reasoning is this: if you keep doing it, eventually, it will get easier. The best way to tackle what you don't like - and get better at it - is to just do it. Nike may have been on to something with their tagline.
So, in the realm of massage business, what are your burpees? Is it public speaking? Your elevator speech of telling people what you do? Online marketing? Asking clients to rebook?
I'm guessing it isn't actual massaging... you've probably got that part down.
Pinpoint what it is about your massage business that you don't like, and just do it. You might just find that it not only gets easier, but you get better at it.
As for those burpees... I'm still working on it.
