Screw societal norms, seriously, name any of them in the 18th century that benefitted humanity asides from wearing clothes, there are norms all around us that we never question, yet don't make any sense if thought about, and thus thinking about them and why they don't make sense destroy them. Questioning this basic bits of life make the world change, change for better or worse is all up to how we react when things change.
Never buy animals from store chains, they basically all come from breeding mills, instead get your fwuffy little ball of love or "I hate being here with you inferior sepcies" if you get a cat, from an animal shelter. Note this is sadly true and you can even google it.

If anyone tells you you can't do something ask your self this "is this a game I am playing and I physically cannot do it/is it against the law?" If the aswer is no science will eventually prove that you can do it, so get a head start now.
Never judge someone on arbitrary factors like gender identity, sexual oreintation, race, ethnicity, or mental or physical disability, only judge them on how much they suck in general and if they judge people based on any of the above factors, because if they do, that probably means they suck.
You are always important to someone unless you really suck at being nice to anyone.
