Never let success get to your head. Never let failure get to your heart.
You don't have enough time. You don't have the proper equipment. You don't have a good program. In reality you just don't have enough heart.
There's no replacement for hard work. There's no shortcut. There's no secret. The sooner you accept that fact the better off you will be.
You think you work hard but there is someone, somewhere, who is willing to work harder than you are. Willing to give more. Keep that in mind
