You need to figure out what the 2 or 3 most important things are, and then just do those.

If it works out, you're going to be working on this for 10 years.

Don't let the company get distracted or excited about other things. A common mistake is that companies get excited by their own PR.

You need to have a culture where people have very high quality standards in everything the company does, but still move quickly.

You only get points when you make something the market wants. So if you work really hard on the wrong things, no one will care.

A related advantage of mission oriented ideas, is that you yourself will be dedicated to them.

Great execution towards a terrible idea will get you nowhere.
