What would you tell yourself about investing if you could go back

[Shane Craig]

I have been investing in real estate for the last five years( I'm currently 30) and have learned a lot. However, I know their is still a lot to learn from experienced investors.  If you could go back in time when you started investing.  What advice or  pep talk would you give?  You can't give information about lottery numbers or stock picks. I'm just looking for information from experienced investors that took them years to learn.
