Most people are soft. There will be so many times in life where you have to keep going when you don't feel like it. My pops pushed me to tears multiple times growing up. There's abuse and there's great parenting. As boys we cry over things that we laugh about when we become men.
At some point you just gotta want it bad enough. The money. The body. The lifestyle. The success. Whatever that “it” is for you. You just gotta want it so bad that you wake up one day & work harder than you ever did. Then one day, you’ll look around & realize you finally have it.
