I liked this comic a lot from Saturday Morning Breakfast Cereal: <a class="postlink" href="http://www.smbc-comics.com/index.php?db=comics&id=2722#comic" onclick="window.open(this.href);return false;">http://www.smbc-comics.com/index.php?db ... 2722#comic</a> In it, he describes how the time it takes to master something means you have the opportunity to master about 11 things over the course of your life. Read the comic, it is worth it. Focus: You can choose any talent, skill, subject, or whatever you want. Whatever it is, you will become a master at it. What are your 11? Provide brief descriptions. Don't just say "Play the guitar." Play what guitar? Like whom? Why? How will you use this skill?
