Implementation is something else. What so-called 'idea people' don't realize is that without implementation, ideas are worthless. And you know what? Implementation is hard.
Starting a business is hard work!
The intangible benefits are pretty great, of course - freedom to set your own hours (clients permitting), freedom to set your own priorities, that sort of thing. That's all great. But the costs are pretty hefty. It's not just the money - though the money is a big problem too!
It's about the stress of getting a business off the ground. It's about taking half pay, living expenses, or no pay whatsoever while the business gets off the ground. It's about hiring someone new and wondering if they're actually a fuckup who's going to pull you down. It takes grit! And after the first year, you end up wondering if you did the right thing - if working for someone else might not seem so bad after all.
I used to guard my ideas jealously, but these days I don't even care. Go ahead, 'steal' my ideas. Then, whether you fail or succeed, I'll watch what you did. And if I have the opportunity... I'll give it my best shot to do it better.
