Have fun! - Don’t get so wrapped up trying to save the world that you sacrifice your own humanity. Having a rich, fulfilling personal life is a well-spring of passion that will only boost your ability to contribute -- not distract you. Trust me: you won’t be sucked into the veil of Maya and forget about your vow to save the world. So have a beer. Call up your best friend. Watch a movie that has absolutely no world-saving side-benefits whatsoever! You should do whatever it is that connects to that essential joy of being human and you should do it as often as you need; without apologies. Enough people sacrifice their lives without even realizing it -- don’t sacrifice your own on purpose.
