With the new year, make one part of your life easier, decision making. Pick something to do exactly the same every morning. It might be the same breakfast every day, the same style of socks, or reading the same news app on your phone. Your morning will run smoother and you will be mentally fresher.
Find a quiet place to sit (or stand, if you might doze off) for a short time each day. Imagine a scene of calm and mentally place yourself in it. When you resume your regular activities, you'll think clearer and be a new you.
Show your respect by holding the door for a senior citizen when entering or exiting a building. It's the right thing to do, and you're likely to get a kind thank you in return.
While traveling abroad, only drink bottled water. Water standards in different countries vary widely, and it's no time to spend a night with an upset tummy.
When visiting the beach, carry a sand resistant beach blanket with you. When you pack your things, the sand will remain on the beach.
