Yes. You can.

You're going to need to work on customer service, collection, sales, development, UX, etc, etc.

There is a LOT you must master.

I just reached the point of depending on being a freelancer for my income. After 4 years of 'practice', I feel I have mastered it.

I'd also add the often-overlooked Management and Leadership skills as-well. So many people have everything else, but don't have these valuable abilities and that is why 90% of people will find themselves in lead position rather than a director position.

...Not that their is anything wrong with a lead position it has it's time and place; but when it's time to move up to a director-esque position; you really need to show you can handle the responsibility of others.
