A couple weeks ago I turned 30. Leading up to my birthday I wrote a post on what I learned in my 20s.

But I did something else. I sent an email out to my subscribers and asked readers age 37 and older what advice they would give their 30-year-old selves. The idea was that I would crowdsource the life experience from my older readership and create another article based on their collective wisdom.

The result was spectacular. I received over 600 responses, many of which were over a page in length. It took me a solid three days to read through them all and I was floored by the quality of insight people sent.

So first of all, a hearty thank you to all who contributed and helped create this article.

While going through the emails what surprised me the most was just how consistent some of the advice was. The same 5-6 pieces of advice came up over and over and over again in different forms across literally 100s of emails. It seems that there really are a few core pieces of advice that are particularly relevant to this decade of your life.

Below are 10 of the most common themes appearing throughout all of the 600 emails. The majority of the article comprises dozens of quotes taken from readers. Some are left anonymous. Others have their age listed.
