What are the three best life hacks?

 Here are some important hacks I've learned throughout my life:

• Always carry a pen with you, especially when traveling (you know that sometimes you won't have another option).

• When you see an animal crossing the road, be sure to stop, look, and wait. There will probably be a few more animals following.

• Use your foot to stop your phone from falling if you drop it (never try this with the Nokia 3310, you could seriously injure yourself).

• When you get together with your family, discuss common scams and life hacks that you know about but they don't.

• If a guest or host asks you if you'd like to take some leftover food home, always say yes. It will likely make them very happy.
• Answer the door wearing a coat. If it's someone you like, you can say you just got home. If it's someone you don't like, you can say you were just leaving.

• If you're selling something on eBay, offer free shipping and add the shipping cost to the main price.
• When sending a long string of numbers to someone, break it into groups of three or four digits separated by spaces to make it more readable.

• If you solve a problem that you yourself posted on a forum, add the solution so that others can use it for the same problem.
• Don't take other people's business more seriously than they take it themselves.
• If someone is introducing you to a song you really like, don't talk during the song unless it's about the music itself or something urgent. That song might mean a lot to the other person, and talking in the middle of it shows that you think your ideas are more important than theirs.
• Pay attention to how your house smells when you return from a trip – it's how it smells to guests all the time, you've just gotten used to it.
• When offering your condolences to someone who is grieving, focus on the PERSON and avoid talking too much about who they lost.

What psychological tricks and hacks are useful to know?

 

1. If someone is trying to make you decide in a hurry, they are probably giving you a bad deal. Walk away.
2. Sometimes pretending that you are naive gets you more information.
1. Pretending is helpful many times.
3. If you want to avoid office politics, say good things about coworkers behind their backs.
4. Physical contact makes you more likely to say yes to a request.
5. If you want to make someone feel uncomfortable, look at their forehead when you're talking to them.
6. When a group of people laugh, they tend to look at the person they like the most.
7. Nervousness and excitement have the same body reaction, so if you're nervous for a speech, instead convince yourself you're excited. Its proven to give better speeches, too.
8. Ask for something that seems small, but is related, to what you really want. Then, once they've agreed to the small thing, just work up with slightly larger requests until you've achieved the desired outcome
