All right, shave only once every three days. At the end of the third day you will have that nice scruffy Yassar Arafat look. Maybe you will get used to the facial hair, and stretch the intervals out more and more. And when you get your beard don't trim it at all or even comb it.
Believe it or not I once had a beard. I did have to get used to the feeling of the beard, and for the first 3 days it felt stubbly. Then the whiskers grew out enough so the beard felt as natural as hair on the scalp.
Yes, make sure you drink beer and eat limburger cheese sandwiches with onions so you will burp and fart. You want your breath able to bubble paint and varnish.
Make sure you wear only the clothes you wear to paint and to change the oil in your car. You also want to wear the rattiest stinkiest gym shoes also.
If you play your cards right, maybe before August your wife will plead with you to shave not only your face, but your legs, arms, and chest. She might even surprise you with giving you a dress, heels, etc. just so you will get cleaned up and presentable.
