People are afraid of immortality because they believe they won't find something to do and will get bored! What to do if we become immortal? We can just walk! It is better than dying!

If you have a complex life, make it simple; if you have a simple life, continue it that way!

There exists no greater megalomania than thinking that we are all alone in this cosmic ocean!

A street that you have never visited is a book that you have never read! You never know what you are missing!

No turtle can be a revolutionist, because revolution requires high speed!

All men start life as a road-user and only few continue it as a road-creator!

Don't live in the castles; freedom is in the fields! But I can also say: Don't live in the fields; security is in the castles!
