I have a good way to motivate myself/make myself feel better after a long day, and that is by having a motivation wall. It’s very simple. All you need is Post-its, a Sharpie and your imagination.
Write a word or a sentence on each Post-it to motivate you/make you feel better/make you laugh. It can be anything. If you like to write books/blogs/stories, have a quote there (I have Ernest Hemingway’s “There is nothing to writing. All you do is sit at a typewriter and bleed.”). If you’re in the middle of studying for a test, or finals, have something to encourage you to keep going. I have “Shut up and revise. Even if it’s maths.” (I don’t like maths, but I’m sure you understood that). Have something to read every time you’re sitting at your desk to remind you how great you are, or how you just have to keep going (Just keep swimming).
And aside from helping you to get motivated, it’s also really nice to look at. Post-its look nice anywhere and everywhere anyway. Decorate your motivation wall however you like, with different colours, styles of writing, doodles, shapes… Go wild!
