Do You Look at Things As Glass Half Full or Glass Half Empty?

I read a lot of people's post here and can understand why some people are just not meant to be an entrepreneur. When someone puts out an idea, some of you keep asking about how it's going to make money or what the business model is. There's plenty of examples of non-money making businesses that turn the founder(s) into millionaires or even billionaires. Look at the creator of What'sApp for example. Even Symphony just took funding. Some of you developers just need to have the mentality of just build things and seeing what happens. By thinking about stuff outside of your expertise like generating sales or how to monetize things, you've already giving yourself a reason not to move forward. Even if there's no real clear business models. Someone will figure out a way to monetize it. Just my Thursday rant. I love this community.
