New entrpreneur - how?

So one time, long ago, I sewed like 20 skirts, and created a web page for which to sell them. Having quickly moved on from that venture, I find myself again, thinking I need to do the entrepreneur thing. I have ideas, but no idea how to get traction. Senior entrepreneurs, do you have any tips? How does one get a business up off the ground?
