What is your all time favorite quote?

Quotes are what make a lot of people feel alive, give them inspiration, make them motivated and keep the flame going. I just read a book (The Almanack of Naval Ravikant") and there are some pretty good quotes in there. I have been following Naval on Twitter for a long time and he is truly amazing and shares great advice regarding business, wealth, philosphy, health and soo on but this one quote in particular got stuck in my head. It goes like this: "To write a great book, you must first become the book." And well, no one wants to read a boring book, where the main character is on the phone all days, goes to a job he hates, does nothing all day and does not take any risks. Why am I writing this? Because I want you to take risk, to live the life you want, to say yes to new advantures, meet cool people, talk to the girl/men you want, work hard for what you want, start a business, work on the idea you have - make your life extrodinary. Think about it. Let's say you would like to write a book when you're 80 years old. Is it going to be interesting? Is it going to put you on your toes? Would you recommend it to a friend? We only have one life and we have to make it count! It's hard, we all have ups and downs but the goal is to never stop living and working hard for what we want! We got this!
