Compliment people- be sincere. See something you like - a piece of jewelry, the color of a shirt and say something. People love it.
Say thank you- send note cards by snail mail, have a stack of little gifts like painted rocks and bookmarks to give to clients- I hand out a lot of hematite, rose quartz, and magnets (law of attraction) and gratitude
Take time for yourself- be intentional, don't fight just to get some space. Nor do you have to be sick or cranky. Make it organic.
Listen to music- turn on the radio, play CDs in the car, sing in the shower, notice that earworms in your head. Find the lyrics, watch the videos, and dance to them.
Love your pets. They are amazing. Enough said.
Don't listen to advice that does not resonate with you.
