Bruce Lee has inspired millions across the globe including UFC champion Georges St-Pierre. For GSP, Lee inspired him in one way with his quote on being like water: formless, shapeless, and being able to take the shape of whatever container it's poured it. Water can flow, crash, creep, or drip And GSP follows this maxim in the sense that he can adapt to any situation; he trains in every area and is so proficient that no matter what the situation he can adapt to it. Additionally, he constantly works on innovating his game so that he can be like water and flow into any area the fight goes to. And also Georges St-Pierre is big on being able to adapt to his environment and make sure he finds a way to become the one that survives and remains at the top.
Also, Bruce Lee influence Georges St-Pierre with his famous quote about not fearing a man who has practiced 10,000 kicks once, but being fearful of the man who has practiced one kick 10,000 times. It's the repetition of one technique that is done 10,000 times that makes it perfect and all the more deadly. GSP is a guy who will go through thousands of repetitions of a technique because he is a perfectionist and it's ingrained into his DNA.
