You want to be an entrepreneur? Then go meet an entrepreneur. Meet as many as you can.
Seriously, that is a better plan than getting a MBA (remember I have one of those), or risking all your hard earned capital, or simply stumbling around in the dark of your ignorance. Go find a entrepreneur and work with them.
Find one, and get to know them, learn from them. I suggest this for two reasons; first you are only as valuable as your network, and you need to start to build one, and second you will discover that they are no smarter than you are. You will watch them and start to think, that you can do that. That is what you want because that is good, the only difference between you and a entrepreneur, is that they took action, and once you take action, good things will start to head your way.
Too often people think they just jump out of a 9 to 5 job, hustle a little, and then the money pours in, but it doesn't work like that. Running your own business means you need to understand how it all works, the better yoiur skill set, the better the odds of succeeding. It is always better to learn from someone who has masde it, learn what they know, see what works, and then move those skills to your own business.
It never hurts to learn more, learn from an expert, and build your network at the same time..
