Foreword by Dana White, president of the UFC -- Why I fight -- Fight night -- I was born ready -- Winning is the greatest feeling in the world -- Everything can change in a split second -- Never underestimate an opponent -- Losing is one of the most devastating experiences in life -- Tragedy precedes success -- Do not accept less than what you're capable of -- Just because it's a rule doesn't mean it's right -- Pain is just one piece of information -- Turn limitations into opportunities -- Trust in knowledge, not in strength -- Know when to move on -- Find fulfillment in the sacrifices -- You have to be the best on your worst day -- No one has the right to beat you -- You will never win a fight by running away -- Don't rely on others to make your decisions -- People around you control your reality -- The end of a failed move is always the beginning of the next one -- Anything of value has to be earned -- Everything is as easy as a decision -- When do you cross the magical boundary that stops you from dreaming big? -- People appreciate excellence no matter who you are -- A loss is still a loss, but it's better to go out in flaming glory -- This is my situation, but this isn't my life -- You can't rely on just one thing to make you happy -- Disregard nonessential information -- Relationships that are easily ruined were never worth much -- Someone has to be the best in the world, why not you? -- Finding a coach is like finding a boyfriend -- You will be tested -- Champions always do more -- Plan out the first exchange -- Nothing will ever be perfect -- If it was easy, everyone would do it -- The only power people have over you is the power you give them -- Winning is a habit -- I'd rather expose myself willingly than wait in fear for it to happen against my will -- Refuse to accept any other reality -- The best fighters are patient at the right times -- There is a moment in a match where it's there for the taking and it comes down to who wants it most -- Fight for every single second -- You have to be willing to embarrass yourself -- Success is the best revenge -- Learn to read the rest beats -- Prepare for the perfect opponent -- Don't let anyone force you to take a step backward -- The answer is: there is no right answer -- I have been there -- The hardest part is knowing when to walk away -- Winning.
