Be grateful for what you have (Happy Thanksgiving, US friends) every day.
Spend more time with the people you like, less time with the ones you don't.
Regularly check in on friends if you think they might be struggling, they might be hurting too much to reach out but desperately need the support.
Don't let your job run your life and occupy your mind every hour of the day.
Learn to listen to understand instead of listening to respond.
Take care of yourself.
