get back on the horse (that bucked you)

get back on the horse (that bucked you)

To return to or resume an activity that one has previously failed at, had difficulty with, or which has previously caused one harm. I know you're discouraged after getting fired, but you need to get back on the horse that bucked you and start looking for work. I've been single for three years since my divorce, but now I think it's time to get back on the horse and start dating again.
