Remember one thing should you ever get "lost".
Being lost is ENTIRELY in your head.
If you knew where you were 6 minutes ago, you CANNOT POSSIBLY BE lost
And please, please, please don't use 4,000,000 pieces of paper and stick post it notes all over everything. Keep it simple and use ONLY one sheet with ONLY what you need on it.
We used to call it "fag packet nav".
