Adam Hinshelwood wants Worthing to learn from Saturday's draw at AFC Hornchurch after Callum Kealy's late penalty earned his side a point.
The hosts hit the woodwork three times in the Bostik League Premier Division 1-1 draw and Hinshelwood felt Worthing's decision-making in the final third was not up to its usual standard.
Worthing went into the match on the back of five successive wins in all competitions but survived an early scare when George Saunders hit a post.
Chances came and went at both ends before Hornchurch took the lead on 42 minutes. Will Miles' pass was cut out by Saunders, who found George Purcell and he fired home.
Purcell struck the woodwork early in the second half, before Worthing were awarded a penalty ten minutes from time. Kealy was brought down by Leon McKenzie and then scored from the resulting spot-kick.
Both sides then almost won it as Saunders struck the bar, while Kealy glanced a header wide at the other end.
Looking back on the match, Hinshelwood said: "We had a chance scrambled away early on and then they hit the post.
"I thought we found our footing in the game, had a lot of possession and got into the final third quite often but we were quite wasteful when we got there.
"Just before half-time, Will's played a pass that has got intercepted by their striker, one pass later and it's in the back of our net.
"If it wasn't for that one mistake we'd have been relatively happy with how the first half went.
"We upped the tempo in the second half and tried to take the game to them. Their chances came on the counter-attack or from us being loose with a couple of passes rather than them carving us open.
"We had a lot of the ball and tried to do our best to get into the final third but whenever we got there our decision making was poor.
"When it's like that, you're relatively pleased to come away with something."
Hinshelwood was disappointed with the goal Worthing gave away and wants his side to learn from it going forward.
He said: "It's one that's going to happen (with Worthing's expansive game) but it was so preventable. You've got to make better decisions and if we're going to play this way, we've got to back ourselves to be better on the ball.
"We can't afford to give the ball away when we're under no pressure when we're so expansive.
"We've got to trust our players with no pressure on them that they can choose the right decision, that's what we've got to get better at.
"We've got to learn from it that if we are going to play this way, then there is a lot of faith in players to choose the right decision.
"It would be very easy to keep everyone compact and just shell it forward but I don't think we've got the personnel and the players to play that way.
"We have a lot of trust in the players. Ultimately we've got to learn from it and make sure we're better."
Worthing remain third in the table with the point. They are now four points behind leaders Dorking Wanderers with two games in hand.
Worthing host Tonbridge Angels in the Velocity Trophy tomorrow evening (7.45pm).
