• exercise more - even for 7 minutes
• sleep more - to decrease sensitivity to negative emotions
• move closer to work
• spend time with friends and family - don't REGRET this on your DEATHBED
• go outside - a short 20 minute walk can help greatly
• help others - 100 hours a year = 2 hours per week
• practice smiling - it can alleviate pain
• plan a trip - but don't even take one - the anticipation alone can help improve feelings of happiness
• MEDITATE - rewire your brain for happiness
• practice GRATITUDE - keep a journal of things you're grateful for, share 3 good things that happened each day with a friend or partner, go out of your way to show gratitude for others when they help you
