Most don't mind sacrifice if it's free, painless, or comfortable. That's NOT sacrifice!
In order to achieve something great, you must give up something great ... usually your time and comfort levels. 1% Success comes to those who are willing to feel pain and struggle, love and embrace it. It may last an hour, month, or 10 years, but the pain will disappear, leaving behind your dreams!
Decide you'll do whatever it takes for as long as it takes. This is true sacrifice.
