Victories can be costly. Many times there are no free lunches.  This means that to achieve many thing, you will have to be prepared to pay the price and give something up - at least temporarily. 

Success requires discipline.

Success gravitates towards people who are willing to lay down everything including their own lives.

How much are you willing to lay down to achieve success?
