My favourite city is Moscow, because of its history, which I find fascinating. As I learned to speak Russian, it made it even more interesting.

The Nile, draining out into the Mediterranean. The bright lights of Cairo announce the opening of the north-flowing river’s delta, with Jerusalem’s answering high beams to the northeast. This 4,258 mile braid of human life, first navigated end-to-end in 2004, is visible in a single glance from space.

Remember, nobody changes the world on their own.

Anticipating problems and figuring out how to solve them is actually the opposite of worrying: it's productive.

There is no problem so bad that you cannot make it worse

Decide in your heart of hearts what really excites and challenges you, and start moving your life in that direction. Every decision you make, from what you eat to what you do with your time tonight, turns you into who you are tomorrow, and the day after that. Look at who you want to be, and start sculpting yourself into that person. You may not get exactly where you thought you'd be, but you will be doing things that suit you in a profession you believe in. Don't let life randomly kick you into the adult you don't want to become.
