Around my late 20's I started to look at &amp; perceive everything differently. I noticed what u said at the end. That we've discovered so much but always stay curious &amp; creative because u might find a new way to look at something no one else has looked at in that similar way so the opportunity for discovery is almost limitless. I know a lot of people these days get discouraged but really u just never know what might be being overlooked or not noticed. (Like geothermal energy options. If we can find ways to incorporate that it would change our world. If we can find new ways to boar the holes without the old methods that don't work. It would change the world. If we can open natural waterways, restore salmon runs/ecosystem/area's in severe drought. We can change the world. We just got to stay creative)
