It is not as simple as it sounds.
You are supposed to go after the things you want. And meet and beat obstacles along the way.
But there are times when you have to keep a delicate balance between the things you want and the price you will or might have to pay to achieve them.
It is difficult enough in the first place to know what you really want. And it doesn’t become any easier when you then have to navigate tricky waters to get to them once you understand or have a concrete idea of what you are going after.
