Ask HN: Should I worry about the low number of authorized shares in startup?

I did something stupid with my incorporation and our delaware c-corp has only about 3000 authorized shares of common stock. I hear that startups should have at least 10,000,000.

My attorney says that I should go in for a stock split right now. What do you guys suggest? Do I need to fix this urgently? Or can I wait till we're ready for some funding or hiring employees? Am I going to face a lot of problems later on?
