One thing that helps is to put tools back in the toolbox when you have finished with them. This means that when you need the same tool 20 minutes later you know exactly where it is.
However this is not the method I use. After years of practice I have perfected the technique of putting a tool down in the most convenient place as soon as I have finished with it. This means that not only at the end of the day you have to go all over the place collecting them but also if you need a tool more than once you sometimes need to retrace your steps back to where you think you last used it, and both of these are very good exercise.
It is even more fun when you have strapped the ladders onto the roofbars and realise you have left your hammer in the gutter, or you have glued and pinned a plinth onto a piece of fitted furniture and an hour later you realise you have left your favourite chisel behind it.
And I'm sure that many people, like me, have had those amusing moments when a tool has simply disappeared off the face of the earth only to turn up two days later wrapped in a dustsheet! Oh what a laugh this can be when you think about the 20 minutes you spent searching for it.
