If you go clubbing or to concerts a lot buy yourself acoustic earplugs. They don’t muffle the sound, just get rid of the harmful frequencies. Tinnitus is something very easy to get and very hard/impossible to get rid of.
When you have an item you changed your mind on at the grocery store (especially perishables) just give it to the cashier. We really don't mind and you don't have to be sorry about it. It makes everyone's lives easier and we won't have to go through the store looking for misplaced items.
If you are given a prepaid debit card as a gift, save it after you spend the money. You can use it to sign up for free trials online without worry of being scammed.
Never give an animal to someone as a gift, especially if they do not ask for one.
Thrusting an animal on someone forces them to take care of another life but not everyone can afford to give it the life it deserves.
If you're trying to learn a new language try watching children's shows dubbed in that language. Children's shows tend to go over things like shapes, colors, animals, etc. and can help you learn basic words and sentences.
When someone says no to a piece of cake, don't try to convince them saying "it's just one piece". It's not just one piece. It's a mentally lost battle that will affect the coming battles, possibly resulting in a lost war against an unhealthy lifestyle for a person actively trying to improve.
If you know someone who cares about everyone around them a lot, please, ask them if they are okay from time to time.
I have seen, with time, that people that care a lot about other people, it's sometimes because they have trouble taking care of themselves.
After college, once you get the first job, start looking for a better job after a year or two. Don't stay out of loyalty.
Because trust me, no company is loyal to their employees. Be respectful and professional, but loyalty in a company is rarely noticed and appreciated.
As a person who has worked for a same company for 6 years after graduating, i found out i didn't get a single raise within it unless i ask for it every f*cking year, never got much other benefit than initially signed while studying at school.
So i started applying for 5 months and finally got a job, it pays me almost 5 (edit: 4 is more accurate+ benefits such as health care, lunch, gym etc...) times as much as i used to. My friend from same school, with same seniority was getting 4 times my salary for the last 2 years already.
My mistake was thinking that being loyal to this company was gonna in return make the company loyal to me, the company only wants lower costs, loyalty has no place here.
If you like one song by an artist, but don't dig the rest of their stuff. Find out who the producer is and see what other work they've done. The producer can play a big role in how the final song turns out.
If your fire alarm goes off, call your pets and give them a treat. Eventually they will come when the alarm goes off, saving you from wasting time looking for pets during an evacuation.
