"Don't sacrifice what you want most for what you want now. Write down what you want the most and see it often." -Peter Vidmar

What this quote is saying is that don't give up on the thing you wanted the most. This quote is most likely referring to those people that gave up on their dream easily. For example, a lot of people gave up on their dream that they really wanted to achieve like a dream job or work at/make a company. But then they do something else they never wanted to do, like a dangerous job or working at a really bad company. What Peter is trying to say is to not give up and try what ever you can to achieve that dream.
