The inverse of that problem is the solution. Then you want to find people in that niche who have had that problem and now have the solution, they will exist. And then once you've found them, you want to see what they're doing differently from the people who just live with the problem. That's how you get your first few clients. But once you've started to get a few clients, it becomes more about thinking big. It's like instead of just trying to solve, I'll tell you how I got started.
What problem are you solving? For who? With what solution? What makes your solution different? And most importantly: What would the perfect solution look like? These are the things you should be spending most of your time thinking about as an entrepreneur. NOT taking photos of your food, Gucci duffle bag, and shitty snakeskin loafers to get social media followers to think you're rich, and maybe buy your stuff. Right now the entrepreneur market is in a state of mass confusion. Why? I believe most people's targets and goals are vague undefined entities. And when you build a mind, business, and strategy based upon vagueness, you build nothing of value and cause confusion. This is why you need to think: What does perfection look like? Defining the perfect solution your customers would dream of in a world unconstrained with today's reality will open your eyes to what they really want. Your goal should be to make progress towards it. Innovation begins here!
