It's harder, but we're still finding oil in Oklahoma today. The bar has been raised on startup companies, but it can still be done. Every regulation and every rule limits you, but, yes, it can still be done. That's the beauty of living in a free country and having the freedom to have an idea and become an entrepreneur.
Consider a tree for a moment. As beautiful as trees are to look at, we don't see what goes on underground - as they grow roots. Trees must develop deep roots in order to grow strong and produce their beauty. But we don't see the roots. We just see and enjoy the beauty. In much the same way, what goes on inside of us is like the roots of a tree.
