Asked if he was comfortable with the seven-point lead, Strachan replied: "Yes - when we only have two games left and can't be caught.
"After a win like that against Rangers, you get about 15 minutes when you think, 'Phew - that was good' and then it's away.
"It's not fair because, when the result goes the other way, it doesn't leave you for a while. It stays with you.
"We're happy with our position at the moment but nobody is looking too far ahead.
"It was only a few weeks ago when we were seven points ahead, we were beaten by Hibs and all hell broke loose.
"The same people who said to me before the game, 'You must be comfortable with your seven-point lead' change it when we get beat to, 'The pressure is on now!'
"You have to strike a balance and, for me, it's right to do that by not reading anything - win, lose or draw."
