A couple of de-motivators that have been mentioned to me by ladies:

Hecklers. OK, it is usually goodnatured and between mates/buddies, but some ladies are apprehensive of it.

Learning the trade. It takes time to be known, and it can be a hungry time, sleeping on settees and saving pennies.

Constant travelling. Away from families and kids and friends.

Certainly, these apply to everyone making their way as a professional, but it may be that the gentle sex feels them more, generally. Do they, typically?
