Horner believes it is vital for teams to claim regular wins during seasons in which they are clearly not challenging for the title, in order to maintain morale.
"I think it's all about winning," the Red Bull team principal told Sky Sports after the Abu Dhabi GP.
"It's all about achieving a goal and I think we went through some difficult years and we never lost sight of what our target was.
"In those difficult years, we were always picking up wins here and there, we never lost that fighting spirit.
"We still operate very much as an old-school race team and we push the limits. We push ourselves and I think nobody wants to let the side down.
"As soon as Honda came back with a competitive engine and suddenly we were in a position to really capitalise on that. I have to pay tribute to them for the role that they’ve played in the reliability that we’ve seen as well."
