Dear Reader,
For as long as I can remember, I have wanted to learn to drive.
Due to an assortment of life events, I didn’t get the opportunity to get
my license until a few years ago, at 28. I hopped into the instructor’s
car on the day of my first lesson, drove through an intersection,
made four right turns, parked haphazardly, and hobbled out of the
car and to my front door, stiff with fear. Everything had gone well. But
at the first traffic light, watching cars race past, I’d had an epiphany:
cars were accursed death traps. I canceled my remaining lessons.
A year passed before I signed up again. When I relayed my previous
experience to my new instructor, he, a college student working part
time at the driving school, nodded knowingly. His adult drivers were
often more anxious learners than his teenage pupils. “You overthink
it,” he noted. “Also, your brains are too developed. More impulse
control, less risky behavior.” (Here he shook his head regrettably, as
if to say that a fully developed brain was an unfortunate
characteristic to possess.) “You need to get out of your own way. Let
yourself be a little reckless.”
ed. Reader, I did get out of my own way. I successfully learned to drive
erv
es
htsr that year and I’m pleased to say that I love it. And I often find myself
g
riAll returning to my instructor’s advice. When I think about adopting new
c..
n
Ig hobbies or learning new skills, I do my best to learn without restraint.

Notes on the Screen Presentation
You are reading this e-book in a file format (EPUB or Mobi) that
makes the book content adaptable to the display options of your
reading device and to your personal needs. That’s a great thing; but
unfortunately not every device displays the content in the same way
and the rendering of features such as pictures and tables or
hyphenation can lead to difficulties. This e-book was optimized for
the presentation on as many common reading devices as possible.
If you want to zoom in on a figure (especially in iBooks on the iPad),
tap the respective figure once. By tapping once again, you return to
the previous screen. You can find more recommendations on the
customization of the screen layout on the Service Pages.
