I have contributed my mite to another horse-related crowd funding project. A Big Name Rider is looking for support to get the next Big Time horse. As with my previous project support [RallyWe], I am not giving the name of the individual involved. OTOH, not many international riders are trying to buy a $500,000 horse from contributors pennies, so it wouldn’t be hard to discover. Still, I don’t want you to think I am shilling for him/her. I know nothing about the dude (I’m tired of the pronoun game). I recognize his name & haven’t heard anything horrid about him, but then, I haven’t really been paying to the international scene lately.
As before, my goal is to follow the process. Therefore, my first – of undoubtedly many – tackbox quarterback comments:
The projects have varying levels of thank you for varying levels of funding and varying durations of updates for ditto. Why? If I had any form of crowdsource project, I would send a personalized thank you by return email. I would then keep you updated on the project in specific and my business in general until you asked me to stop. Ninety-nine plus percent of the effort would be wasted. However, one person might say, ‘Oh, this is kinda fun. Why don’t I take a lesson, attend a clinic, buy him/her a horse.’ John Wanamaker is attributed with saying
“Half the money I spend on advertising is wasted; the trouble is I don’t know which half.” [The Quotations Page]
I would think one would want to spread the word even more so these days now that communication is so comparatively simple: no cumbersome collating, no stamps, no address databases. Just type, click, & go. Granted, I’m a writer, so this would come easily to me. However:
a) Keeping the owner(s) happy is part of being paid to ride.
b) If the rider is not comfortable with the written word, surely there is a student, owner, employee, family member who would be willing to trade PR flack duties for love or lessons.
Personal Note
32 years ago I made the decision to keep my riding as a hobby. I have yet to see anything that makes me regret that decision.

I remember the decision well and it was a good one. Shifting off between passion and profession provides counterbalances. Since you commit 100% to anything you undertake, combining them would leave you where?
Personal note: in a single week, years ago, I did two things I had never done before, both stressful in anticipation, both successful in the outcome: I gave a prepared speech to 120 professionals about their profession and I made my first deep scuba dive.
Extreme opposites or what? If I had not been able to cross-rough from one anxiety to the other for relief, neither would have been as much fun as it was. I think a different go-to activity was crucial.
In your case, Candy Crush would not serve to balance your heart’s delight. I am so glad you ride for your own pleasure and the pleasure of others in your riding is secondary.
