To fly,we have to have resistance

All the powers in the universe are already ours. It is we who have put our hands before our eyes and cry that it is dark.

Learn from yesterday, live for today, hope for tomorrow. The important thing is not to stop questioning.

All changes, even the most longed for, have their melancholy.

Truth is the only safe ground to stand upon.

Some pursue happiness, others create it.

Hope springs eternal in the human breast.
