whats the purpose?

From hunter and gatherer to shooting a huge metal can into space. With all this tech and convenience one could assume 2000 years ago that our everyday life must be pretty relaxing. Is it though? The level of abundance we have in our lifetime might freak us out. Try out everything, so you can know what you want to do. But in a world of so much abundance, someone with little knowledge in many different areas isn't really of any value. On the other hand, picking a specific field, sticking to it and getting really good at it is worth so much more.
