What does the red mean?

[v0031]

Some of the smartest people continuously struggle to get ahead because they forget to address a few simple truths that collectively govern our potential to make progress. So here’s a quick reminder:

#1 – Education and intelligence accomplish nothing without action.
#2 – Happiness and success are two different things.
#3 – Everyone runs their own business.
#4 – Having too many choices interferes with decision making.
#5 – All people possess dimensions of success and dimensions of failure.
#6 – Every mistake you make is progress.
#7 – People can be great at doing things they don’t like to do.
#8 – The problems we have with others are typically more about us.

Sorry if this response is a little late, but...

1. "address" in this context means "take care of" or "deal with"- saying "he addressed the problem" is the same as "he took care of the problem" or "he dealt with the problem".
2. "Everyone runs their own business" could be either people literally own a business or everyone keeps to themselves.

That means the majority of of people own and manage their own companies or workplaces.
