Scotland interim coach Scott Johnson insists the squad much adopt a ruthless mentality if they want to compete.
Johnson watched the team battle bravely in the 23-16 defeat to France in Paris, but reminded his players that luckless defeats count for nothing.
"We have to get rid of the mentality that near enough is good enough," said Johnson. "We've got to learn the habit of putting sides to bed.
"There's been progress but like all things it has taken steps forward in some areas, steps backward in others. It never comes as quickly as you like it to.
"We're under no illusions where we are. The game of rugby is constantly changing as it always does and you have to take note of that and move with it."
Johnson did have some praise for his back line after the Stade de France defeat though, and he feels the Scots have something to build on for the future.
"I was really, really proud of our defence, it was superb," Johnson added.
"However, the flip side of the coin regarding our play was our kick returns were not good and that allowed the French to put us under pressure time and again.
"They have given 100 percent and I salute their resolve."
