Wiser Than Randall G. Leighton

I received an email with the following quotation at the end:

Work like you don't need the money, love like you've never been hurt, dance like no one is watching, sing like no one is listening, and live like it's heaven on Earth.

It was attributed to "anon." A quick search reveals that this quote has been attributed to Randall G. Leighton, Mark Twain and Satchel Paige (three of America's greatest Presidents).

Regardless of the identity of the wisdomer who imparted this wisdom, there are a few obvious omissions:

Dress like you don't have a mirror
Watch like the TV is interesting
Write like anyone gives a shit
Drive like you won't see tomorrow
Stalk like the restraining order has been lifted
Screw like your friends are all watching
Speak like no one understands you, and
Spend like no one is hungry
