If you have a business to start, just do it! If you don't yet have one, but know that's what you want long-term, the very best thing you can do is 1) learn to be an expert in selling and all aspects of building sales teams. Unless it's Ecom, you'll need to generate sales... this gives you the backbone of that, and 2) stack a ton of cash while learning to be a bad a** in sales! From my experience, becoming an ultra high-performer via commission based sales is the fastest way to save tons of money.... Which means you can fund your startup and get it further along before needing to raise money and getting diluted. Sales cures all!
