Be kind and pleasant to the people around you. Your kind words mean a lot to someone.
Don't assume. Because assumption is the mother of all mistakes.
Give up your seat to an elderly person or lady (especially a pregnant woman) on public transport.
Social networks that made it possible to create an apparently high-quality life, where people falsely present themselves, put pressure on the users in society, because they started thinking "I have to do the same".
No one on social networks (or hardly anyone), shows their bad sides and the problems they live with.
In addition to all the negative features that social networks have brought, the only good thing that I have seen in recent months is that they are used in situations of media darkness, in the country where I live. Through social networks, people now share information and find out what was denied to them in other information media.
Yeah, one of your items was on my list already, the other two were ok though.
