I guess people have different meanings to the word- sacrifice.
To truly sacrifice something you need to distinguish between WANT and NEED.
If you want the shiny toys then you have to work more and if you work more then you will have less down time - it is YOUR decision - the thing is if you are a middle class blue collar worker then you must decide- what is your priority- ?
Can you sacrifice ?
Think of what is MOST important to you and work it from there.
And remember that time is not always promised us so think of your goal , of what you want to work toward and work for- and work toward it and be willing to sacrifice for it.
