Jumping off the Cliff into the unknown world of Business Ownership

I am terrified! I have absolutely no idea what I am doing

I feel like I have just arrived on a foreign planet and everyone else has three heads and four eyes on each of them, and they’re all eating alien bird foie gras for breakfast with their clients and I have one head full of nothing and a plate with some vegemite toast on it and no clients. What the hell am I doing here?
