Cash! Should the company go bust, you get fired, you can't work, etc. you must have a backup! I keep 3 to 6 months worth of cash on hand in a savings account that is at a bank not accessible from my day to day bank. That way I am not tempted to spend it. I never look at it. Ever. If you do decide to go with the stock options have $50 of your direct deposit each paycheck go into the above mentioned savings account.
