The best piece of advice I ever got was the following : when you meet or are about to meet someone who is imposing, or important to you, and this makes you nervous, or unsettles you in any way, never forget that how big and mighty, how powerful and awe-inspiring that person may be, at one time or another in their life, that person was on his or her hands and knees with explosive diarrhea, praying to their God for a hasty end to aforementioned rear-pipe decompression. Visualising the subject of your idolation in a state of agonising flatulence will pretty much level the playing field you and that person. Gone is the anxiety.
