Enjoy the people in your life who make you happy and allow yourself time with them. If there are not enough hours in the day, maybe it's time to explore new time management techniques. Make lists and prioritize goals. Talk with someone you know who successfully accomplishes a lot and ask for tips. Visit the local book store or library for self-help material.
Laughter is often the best remedy for stress.
Find reasons to laugh. See a funny movie or visit a comedy club. When you feel your temper rising, count to 10. This will give you time to calm down and keep you from saying something you might regret later. If 10 is not enough time to calm down, keep counting.
