You can always make more ideas, but you can’t make more time. If you decide to work on an idea, make sure you’re serious about it. Sleep on it, think about it, share it with other people. If you’re still crazy passionate about it, then do it.
If you want to improve, be content to be thought foolish and stupid.
If you are really effective at what you do, 95% of the things said about you will be negative.
The power of population is so superior to the power of the earth to produce subsistence for man, that premature death must in some shape or other visit the human race. The vices of mankind are active and able ministers of depopulation. They are the precursors in the great army of destruction, and often finish the dreadful work themselves. But should they fail in this war of extermination, sickly seasons, epidemics, pestilence, and plague advance in terrific array, and sweep off their thousands and tens of thousands. Should success be still incomplete, gigantic inevitable famine stalks in the rear, and with one mighty blow levels the population with the food of the world.
At some time in the relatively near future, we will have both the computing power and the brain knowledge to be able to create artificial realities that we will be able to plug our brains into that will give no indication that they are anything but real. We will be able to create any kind of reality, any kind of experience you can imagine.
Once a civilization is able to do that, it may very well be that they will have no other desires beyond increasing their computing power, extending their life spans, and protecting themselves from planetary disasters. This might be the key to the fact that we have not detected any advanced civilizations.
