I want to start a few riddles so that I can just relax a bit from my other projects.

First one:

Everybody needs me

Everybody deserves me

I can be bought but only with time

Once you have me you can lose me

But I am always there, never leaving

What am I?

When you stop to look, you can always see me. But if you try to touch me, you can never feel me. Although you walk towards me, I remain the same distance from you. What am I?

You measure my life in hours and I serve you by expiring. I’m quick when I’m thin and slow when I’m fat. The wind is my enemy. What am I ?

I have cities, but no houses. I have mountains, but no trees. I have water, but no fish. What am I?
