Conjurer of internet magic

I know we are still a month away from the new year, but one can never be too prepared for it.  I was challenged the other day about the impact that a person can have by preparing for the future.  The question proposed to me was as follows:

What should you start doing today that 10 years from now you'll be very happy you started doing?

My goal at this point is to figure out the answer to that question by the end of the year.
