As a 22 year old, I find this to be a practical, inspirational and not (too) cliched list. Thanks Jason Nazar 

The list is good, but 20 things is a lot. Here are the three I think are most important:

Time is Not a Limitless Commodity – I so rarely find young professionals that have a heightened sense of urgency to get to the next level.  In our 20s we think we have all the time in the world to A) figure it out and B) get what we want.  Time is the only treasure we start off with in abundance, and can never get back.  Make the most of the opportunities you have today, because there will be a time when you have no more of it.

You’re Talented, But Talent is Overrated - Congratulations, you may be the most capable, creative, knowledgeable & multi-tasking generation yet.  As my father says, “I’ll Give You a Sh-t Medal.”  Unrefined raw materials (no matter how valuable) are simply wasted potential.  There’s no prize for talent, just results.  Even the most seemingly gifted folks methodically and painfully worked their way to success.  (Tip: read “Talent is Overrated”)

We’re More Productive in the Morning – During my first 2 years at Docstoc (while I was still in my 20’s) I prided myself on staying at the office until 3am on a regular basis.  I thought I got so much work done in those hours long after everyone else was gone.  But in retrospect I got more menial, task-based items done, not the more complicated strategic planning, phone calls or meetings that needed to happen during business hours.  Now I stress an office-wide early start time because I know, for the most part, we’re more productive as a team in those early hours of the day.

I don't stress an office-wide early start time, by the way.

The reason I am so productive in the morning is that I don't have to deal with anything at the office.

I can just focus on what is most important.
