The 5 P's: Prior Preparation Prevents P%ss-Poor Performance. (Maybe that's 6 P's then).
Remember a well prepared flight plan always helps. Make sure wind drift has been applied correctly, fuel figures added up correctly etc. (double check) Make sure you have a watch with the correct time set. The amount of times I had students show up without a watch on their Navs
Also plan your arrival at the other end. Brief yourself well in advance on how you're going to join the circuit etc. Its one thing finding your way to the destination, but it another to correctly join the circuit (especially if there are right hand circuits or noise abatement procedures).
So basically its a matter of being prepared, staying well ahead of the aircraft and as Ultralights said, not losing sight of the big picture
It all comes with practise
