He captured strange and distant worlds in greater detail than ever before. They were beautiful, magnificent, full of awe and wonder. But beneath their sublime surfaces, there was nothing: no love or hate, no light or dark. He could only see what was not there, and missed what was right in front of him.
Anything in life worth having is worth working for.
— Andrew Carnegie
Basically what this quote means is that if you want something enough, then you will do whatever it takes to get it. Nothing can ever stop you from doing anything in your power to achieve that. If you consider something worth having, it is of course worth fighting for. That sounds more than fair.
