hello @abigail-dantes as always an excellent post full of knowledge that help us understand the purpose of psychology.
As for mindfulness, life and reading of course taught me to find some exercises to turn it into a habit that helps us understand acceptance and be present I will share with you.

Some of them are meditation: which helps us or allows us to understand our mind to return it or bring it back to the present moment makes us eliminate the complicated part and make conscious. It is done daily for at least five minutes and you increase the time as the days go by.

read: look for a moment of tranquility in which you feel alone, relax and read a novel or any book that you find interesting and you like, try not to have the TV or any device nearby at that time this will put into practice your approach

draw: grab a paper and a pencil and just start drawing do not think about anything else only what you want to capture and if your thoughts go from one part to another comes back with placidity to the present moment not to teach the final drawing to anyone will help to draw without fear. Although there are many more exercises these three are the ones that I have put into practice and they have helped me to practice mindfulness.

I hope you continue to guide me with your posts that are of great help to improve us as human beings greetings ..
