Arnold Schwarzenegger, Isadore Sharp, and Ben Horowitz

The Struggle is not failure, but it causes failure. Especially if you are weak. Always if you are weak. Most people are not strong enough. Every great entrepreneur from Steve Jobs to Mark Zuckerberg went through the Struggle and struggle they did, so you are not alone. But that does not mean that you will make it. You may not make it. That is why it is the Struggle.
