But to go to a place like Northampton and dominate the team who lead the way in England for 35 minutes and build a 15-point lead, only to come away with nothing, has made me even more determined to get the win we must produce against Ulster tomorrow night.
It is also an experience that has left me confident we have another 20-30% we can get from the squad of players we have at Glasgow right now.
Obviously the level of knocks we have been picking up is becoming an increasing concern. Prior to the Northampton game we had 11 injuries to key players and we added another three to that number on Sunday.
As a result, we have been delighted to sign Argentine international tighthead prop, German Araoz, on a three-month contract. If he can make the same impact as Ofa Fainga'anuku, then I will be delighted.
Of the new additions to the casualty list, Sean Lamont is a definite non-starter tomorrow.
That is a great pity because I thought he was immense against Saints both defensively and offensively, as he showed when he scored a try.
However, there is no doubt that the key area of improvement which is required in our performance against Ulster will be in our defence.
Prior to the Northampton game, we had defended very well indeed but particularly the second try we conceded, just before the interval, was a very poor one to suffer.
Of course we can argue that the level of injury we suffered and the amount of players that were then forced to play out of position caused so much disruption that we were always going to struggle.
But regardless of that we can and we must do better against the form team in Europe right now, and the only unbeaten one, Ulster.
Defensively, they are rock solid and in attack they have a number of players, like Paul Marshall, who are playing at the top of their game.
So right now this is the ultimate test for us, but the great thing is that it comes on home soil at Scotstoun.
From the way the tickets have been selling out, and with the need to erect an extra terrace, there is no doubt that this tie has captured the imagination of our support and, combined with the Ulster fans, a memorable atmosphere awaits.
What we have to do is produce the type of performance that will really get our supporters involved in the game.
We saw at Northampton during that first 30 minutes or so how a home crowd that is amongst the most vociferous in Europe can be quietened if the opposition take control and get on the scoresheet early on.
So what is absolutely vital for us is that we start well against Ulster and get the scoreboard ticking over early if at all possible.
This is about putting it all on the line and producing the type of performance that will make the Glasgow fans proud to support the Warriors. We're determined to produce just that.
