The critical ingredient is getting off your butt and doing something. It’s as simple as that. A lot of people have ideas, but there are few who decide to do something about them now. Not tomorrow. Not next week. But today. The true entrepreneur is a doer not a dreamer.
Keep on going, and the chances are that you will stumble on something, perhaps when you are least expecting it. I never heard of anyone ever stumbling on something sitting down.
Most 'impossible' goals can be met simply by breaking them down into bite-size chunks, writing them down, believing them, and then going full speed ahead as if they were routine.
