As a football player, sometimes you go on the pitch and think you are invincible.
The other end of the scale is you don't know where your next result is coming from and everybody is reminding you of your record and how you cannot win.
In terms of their away form, this latter instance is what Celtic's players are facing as they go to Old Trafford in the Champions League on Tuesday.
In 16 away fixtures in Europe's elite competition, Celtic have lost 15 of them, drawing only once back in 2004.
That sort of thing weighs on your mind and, as soon as you can break that terrible record, the better for everybody concerned.
The Celtic manager Gordon Strachan will be positive, as he has to be, but I've been in a dressing-room before where a poor run of results can prey on your mind.
We had a bad record against Leicester while I was at Liverpool and, when you sit there before the game, you've got to have a very strong mind to keep it out of your thoughts and concentrate on the job in hand.
As much as the manager and the coaches tell you to forget about it, as a player you can't, so you're up against it before you start. Then you've got to go to Old Trafford to try to beat a team that won the Champions League last year.
However, I think Strachan will be saying there is no better place to break the terrible run than in Manchester. It's vitally important that Celtic do well because, the longer this run goes on, the harder it will be to break it.
The pace of our attack could well see them off
Manchester United are playing incredibly well. They got off to a slow start, but now Wayne Rooney is firing on all cylinders and it will be an amazing atmosphere at Old Trafford because it always is when Celtic play.
That might actually go against the visitors because, when you've had a bad run and you're struggling to win away from home, sometimes it's better that the atmosphere is really flat because the home side can pick...
