Be methodical with planning on the ground, think through on the ground what you are looking for what you are going to do next.
In the air don't forget to: Fly the aeroplane fly the aeroplane and fly the aeroplane. Keep your eyes outside.
Choose sensible fixes, only pick up map 2-3 mins before that fix to identify, ie ten minutes between fixes, map is down for 7 mins. If you need to make a correction do it but between fixes, fly the aeroplane.
