Do something worthwhile so that you achieve a goal larger than yourself. This could mean doing charity work or helping out a friend.
Work it out
Do more exercise. Research shows that taking exercise for at least 30 minutes a day, three times a week, fights depression.
Cultivate gratitude. At the end of each day, write down three things you have felt grateful for, such as having a nice meal or speaking to your mother.
Don't become obsessed with how you feel. Bad feelings don't last. Worrying too much about something without taking action to rectify it will make you feel worse
Spend more time on hobbies and things that you find are absorbing and stimulating.
Watch less television. Watching TV is not a rewarding experience and usually leads to boredom and apathy.
Spend time with loved ones and cultivating relationships.
You'll get by
Spend more time with friends and the people you like. The most successful happiness boosters can be the relationships we have with other people.
Just a Job
Do not let your job overtake everything else in your life.
Use an Ad Break
Cut down on exposure to advertising, as it encourages you to compare yourself with other people and ultimately to feel dissatisfied with what you have.
