Public choice

I am really tired to go agains the stream. It is so difficult to do something first on your own and at the same time to explain to people why it is important to do. One persone can not change the whole world, that's no doubts. One persone can change a bit "public opinion". There is one thing I can not understand, why are people afraid of new things, why don't they do something, what does not cost them anything... Ufff, people are lazy, ignorant and selfish... quite often. But I still hope most of them are nice, kind, active and know what solidarity means.
