Substitute Ryan Fraser and defender Steve Cook scored in the space of three minutes before Nathan Ake netted the stoppage-time goal that secured Bournemouth's first ever win over Liverpool.
“I don't think I'll ever forget this one,” Howe told the club website. (www.afcb.co.uk).
“At half time we were in real trouble. Liverpool were excellent and really showed their quality. Despite that though, the players never lost their self-belief and that's huge.
“There was a real contrast of emotions.”
Howe wants 10th-placed Bournemouth to show the same grit through the rest of the season.
“That's the most pleasing thing... we've maintained that spirit and further enhanced it,” he added.
“It's something we've tried to protect from our promotion from the Championship. We didn't want to lose that spirit and our honesty going into the Premier League.”
Bournemouth travel to 14th-placed Burnley on Sunday.
