Carlos Corberán believes Albion rescued a last-gasp draw at home to Watford on Easter Monday as a result of "not giving up".
The Baggies trailed 2-0 to the Hornets heading into the final 20 minutes of the encounter at The Hawthorns following efforts from Edo Kayembe and Mileta Rajovic.
Brandon Thomas-Asante pulled one back from inside the box, prompting a switch in momentum and wave-after-wave of Albion attacks.
Eventually, in second-half added time, Darnell Furlong crashed one in from outside the penalty area to earn Corberán's team what could be a crucial Sky Bet Championship point.
And the boss says Thomas-Asante's goal was a big turning point.
He said: “If you analyse the minutes of the first half, we were better than them and created more chances but couldn’t score a goal.
“In this type of game, you can never drop the energy levels in any single moment because we’re playing against a very physical team, with players with the legs and energy to compete.
“After minute 52, I think we started to drop our normal level and they were using more spaces to their advantage. They then create chances and score two goals that made everything look very difficult to achieve something positive today.
“But in football, you can never give up and in football the goals can change the feeling and momentum, for the fans and the players, and I think after Asante scored the first goal, the team with the fans and the players who came on off the bench, changed the momentum.
“We drew and were close to achieving something else, so this has to be a lesson for us.
“The key to be unbeaten in eight games, and to have lost one in the last 12 games, is not based tactically or based on us playing the best football because in football, things aren’t going to work how you want them to.
“So in these moments, what’s important is the resilience, is to not give up, to insist, and even when you are not much better than the opponent, don’t allow them to be better than you.
“That’s why, mentally, the team had the right answer in a game which looked impossible to achieve a point in and in the end, the team achieved a point.
‘The two goals were very difficult ones and very good goals.
“The players from the bench helped us score the goals because, for example, a player who didn’t score a goal like Grady (Diangana), he was involved in the previous action of both goals.
“And after, Asante showed great finishing and Furlong scored one goal which was completely unbelievable.”
