Two quotes that have helped me in the last two years or so (in different areas of my life) are:
"No man is your enemy, no man is your friend, every man is your teacher" ~ Florence Scovel. This has helped me to take disappointment in people and rationalize it.
and
"If a thing is worth doing, it is worth doing badly" ~ G.K. Chesterton. This has helped me have patience with myself.
A few songs you can check out:
Jacob Lee - Demons
Peter Raffoul - Fucked Up Together
Jack Kays - Outrun Myself
I don't have any movie or show recommendations, I pretty much just watch The Office and Superstore on repeat.
