Snooker can be a frustrating game, even at professional level.
If you've ever played down your local club, you will know just how hard it is to master the game, but when you see the full-time pros make similar errors to you, it certainly does make you feel a bit better.
And, that's exactly what happened with none other than John Higgins at the Crucible this year.
The four-time world champion looked in fine form from the off, taking a 5-3 advantage into the second session.
Kyren Wilson started slowly in his first semi final appearance at the Crucible, but commendably fought his way back from 4-1 down.
With Higgins leading 7-5, things began to unravel for the Scot in the 13th frame.
The former champion was shaping up to pot a relatively simple red into the bottom left corner pocket after a sloppy safety shot by Wilson.
Higgins completely miscalculated his shot and ended up somehow hitting the black instead. The Scot looked in disbelief at a shot that cost him the frame as Wilson pinned him back to 7-6.
Higgins came through a nail-biting final-frame decider against Judd Trump late on Wednesday night, and the it appears the stress and tension of his quarter-final match has taken its toll on the four-time world champ.
Wilson, a first-timer on the one-table set-up, revealed all on his violent and chequered past within the sport: “I was absolutely terrible, if we were at an amateur event, I’d bang my cue on the floor and the kids at the other end of the room wouldn’t need to look, they knew it was me.
“I used to get stick for that. I’ve never told my dad this, but there was a cue he bought me and I lost my temper in the snooker room they built for me.
“I threw my cue down, snapped the top off, and told my dad that I accidentally fell on it. You need strong emotions but have to learn to control that fire to achieve and I have.”
