Never Stop Learning

The internet has ensured that there will never be a shortage of information or tutorials or resources.

You may have some great skills, but you should always add to them.

Are you a good musician?  Learn a different style.  Learn a new recording technique.  Learn to sing.  Seek out new music theory.

Are you a good writer?  Learn new features of your editing software.  Study some grammar.  Seek out new words.

Are you a programmer?  Study some new math.  Make 'hello world' in an unfamiliar language.  Enter a programming contest.

There's always a field just next to yours that you may find a lot of fertile ground in.  Never stop learning.
