What can I learn in 5 minutes that will be useful for the rest of my life?

• Remember the last three digits on the banknote you are giving to the shopkeeper

Ever be that you gave some money to the shopkeeper, but also he denied getting any money after you bought the product? Constantly make it a habit to remember the last numerals. 

 That way, you can just tell him the number that was on the note you gave. 

• Instead of apologizing for doing something wrong, thank your counterpart for tolerating it.

For example, you made your friend wait 10 mins for you downstairs so, you could finish getting dressed. Instead of saying “sorry, I'm so late”, say “thank you for being patient”. It sets a positive tone instead of a negative one, which is really nice. (I'm not sure how well this would work for bigger, more serious problems, however.) 

The alternate thing is something I have gradually mastered on my own. Appreciate the little things. And I do not mean, go pretend like this one flower is the most precious thing you've seen. I mean more like how you liked someone bought you a carrot cutlet muffin out of the blue, or perhaps your pen was writing redundant easily moment, or you hit all green business lights on your way home. 

• Power Breathing-slowly and deeply. 

Some people have been known to have surgery without anesthetics and just power breathing. It has been said that life can be measured by breaths taken, rather than times lived. Use'em up sluggishly, with good quality. One practice is to gobble through the nose, completely, and slow. Hold at the top of the inhale as long as is comfortable. Exhale slowly and evenly. However, you are holding too long, If you have to stop and breathe typically to catch your breath. Try to do 5 cycles. With practice, breath-cycles, will increase in depth and duration. However, do not do it without medical authorization, If you have high blood pressure. But breathing more slowly, deeply, and resignedly deeply presumably will not hurt anyone. Another practice is to take a full inhale, also count out loud, aloud, while you exhale, starting at 1. Still, you've got good breath capacity, If you can get to 100 before the end of your exhalation, and you can hear easily the figures you are saying. This will enhance internal clarity, blood rotation, and calm the jitters. 

• 1- Primacy and recency: People most remember the first and last things to occur, and barely the middle.
  When scheduling an interview, ask what times the employer is interviewing and try to be first or last.

  2- If you ask someone a question, and they only partially answer, just wait.
  If you stay silent and keep eye contact they will usually continue talking.

  3- People will always remember not what you said but how you made them feel.
  Also, most people like talking about themselves, so ask lots of questions about them.

  4- When you're learning something new, teach it to a friend. Let them ask questions to you related to it.
  If you're able to teach something well, you can be sure that you've understood it very well.

  5- If you get yourself to be really happy and excited to see other people, they will react the same to you.
  It doesn't always happen the first time, but it will definitely happen next time.
