Essays on philosophy, with practical life examples

I need a book that will accompany me before going to sleep (helps getting to sleep).
Also while traveling. It won’t be a regular read so essays are best suited for theses times as I don’t want to be attaced to a time frame to finish it.

Topics that I’m interested in: existentialism, rationalism, relativism.. your suggestions are welcome as well.

I prefer it to be easy read, as I’m just discovering this world.

Thanks
