In the past one company I worked for had a draft hitch for advertising. That was how I got involved with drafts. Horse time was in addition to office time. I didn't have kids so all the extra was not an issue. Just not OT as she paid under a different account and the fringe benefits were great. Free housing, paid working vacations, my training was paid for, travel expenses comped, met some great people and was able to do some incredible things.
Some horse people change their horse, they change their tack and discipline, they change their instructor; they never change themselves.
