When you've got a team who are making a concerted effort to make a batsman feel uncomfortable it can look pretty ordinary.
Consistency in selection is great but it's a whole lot easier if you've got players who warrant that consistency through their performances.
But if you have got a batsman out three or four times in the same series then you are in business - all of a sudden you have got yourself a bit of a bunny.
If you have knocked over a batsman once - fine, it happens. Twice, OK. But more than that in the space of a few Tests then there is definitely something to work with.
The more you get a batsman out the more it becomes psychological. A batsman starts thinking about it and making something of it in his head.
I used to come out and say I was targeting certain players in the opposition team, particularly players I had had success against in the past: Gary Kirsten, Brian Lara and Michael Atherton, for example. It is a mental part of the game.
The Australian team that I was lucky enough to play in had a certain aura and sometimes you had teams beaten before you even walked on the field.
When you're playing in a good team where you're confident in yourself and your team-mates, when you've done the business before, it makes it so much easier.
As a bowler it's a strange feeling when you start running through a team. You get that one wicket under your belt and suddenly you start running in feeling loose, feeling relaxed and thinking about what you want to bowl rather than focusing on trying to force that wicket.
If you get on a roll - good or bad - it's hard to get out of it, but it's not impossible.
When I played in the Australia team the captains were all nerds. Allan Border was a nerd, Mark Taylor was a nerd, Steve Waugh was definitely a nerd and Ricky Ponting too.
That was how we categorised ourselves in the dressing room - you were either a nerd or a Julio. Julios have got to look perfect - the hair has got to be perfect, they've got to have the right gear on, it's all about their appearance. The nerds weren't bothered about how they looked.
An Australian prime minister once said that his job was the second most important job in the country - behind being captain of the cricket team. It's not a job you take on lightly.
If the batsmen can give the bowlers a day and half of rest then that is going to work in the team's favour.
One of the great things about cricket, and certainly something that I found helpful, was that as soon as you step over the boundary rope you can switch off everything that is happening off the field and focus solely on what is happening out on the pitch.
You're always going to get different personalities within a team.
Sometimes when things are happening outside the team, when forces are at work to try to break the team apart or cause issues, it can actually have a different effect - it can bring the boys closer together. They become more of a unit and they start to protect each other.
I loved playing at Lord's - I ended up with 26 wickets at 11.50 from three Tests there. Maybe the wicket, because of the slope, was perfect for my style of bowling.
The best thing about Lord's isn't the slope, it's just being there.
Standing at the end of your run with the ball in your hand preparing to bowl the first ball of an Ashes series is an amazing feeling.
