These are really valuable - only cry when it's necessary. Cry because it hurts and you feel an emotional need to cry, don't do it because you think it gets you more attention, that'll wear out in a hurry. (Also: Don't make trouble or drama where there is none.) - Definitely don't take the yourself too seriously. There's enough to be serious about in the world already, without polluting it further with too much of yours. - Don't give up just because you make a mistake or failed once... or 999 times. We wouldn't have anything we know in this world if scientists and inventors gave up on every failure, most famously: The light bulb. If you think something can be done and the result is worth the effort, stick at it until you get the result you're looking for. That's how we make progress.
