Wish someone had told me this when I was younger.
"Take things more easily. Don't ask yourself so much whether this or that is good for you. Don't ask your conscience so much -- it will get out of tune, like a strummed piano. Keep it for great occasions. Don't try so much to form your character -- it's like trying to pull open a rosebud. Live as you like best, and your character will form itself. Most things are good for you; the exceptions are very rare. (...) You have too much conscience. It's out of all reason, the number of things you think wrong. Spread your wings; rise above the ground. It's never wrong to do that." Henry James
