Don't accept the excuse of complexity. A lot of people will tell you, this is too challenging, this is too complicated, yeah well I know other people simplify but that's not for me, this is a complicated business. They're wrong. You can change the world in 140 characters.

You really need to spend a lot of your time focussing people.

Any executive, any CEO should not have 1 management style. Your management style needs to be dictated by your employee.

Force yourself to simplify every initiative, every product, every marketing, everything you do.

Building a company is basically taking all the irrational people you know... Putting them in one building and then living with them 12 hrs a day at least.

Most people, most great people even are ammunition. But what you need in your company are barrels. You can only shoot through the number of unique barrels you have, so that's how the velocity of your company improves... is by adding barrels, and then you stock them with ammunition and then you can do a lot.

What you actually want to do with every single employee, every single day is expand the scope of their responsibilities until it breaks.
