You must also become very good at your job.
Resolve today to join the top 10 percent in your field, no matter how much effort and sacrifice is necessary and no matter how long it takes.
Everyone in the top 10 percent of his or her field had to start somewhere, most of them in the bottom 10 percent.
Brian Tracy, in his book "Focal Point"
私たちはたしかに市場の頂点にあるものしか選んでいないですね。食べ物でも耐久消費財でもサービスでも。
