Ignore most of what people tell you — you’ll have to figure out the importance stuff for yourself; no one can tell you.
And you know what they say about attachments — avoid them. People. Possessions. Et Cetera. You really don’t need much.
The more excess crap you eliminate from your life, the better off you’ll be.
I’ve gotten to the point where it’s almost not worth telling anything to anyone. It’s a lot easier just keeping everything to myself and experiencing life by myself.
Remember, nothing is very important; nothing means very much. It’s not a big deal, any of it.
Just let it go.
Live, and try to enjoy it.
