1. Laugh Out Loud
2. Expect Less
A lot of what makes you depressed is rooted to expectations. Think about it: why are you angry/sad about something? Because you didn't expect it. Therefore, become a happier person by setting your expectations lower. Notice how I said "lower" and not "minimal". Setting your expectations to a minimal level leads to pessimism, which is not what you want at all.
3. Be with Friends and Family
If happiness is the sky, then friends and family are the stars. You cannot live a happy life without people who you can rely on. Friends and family are essential to one's happiness because they provide love, support, and joy. Therefore, build a framework of friends and family that you know would be there when you need it.
4. Pursue your Passions
How do you be happy? By doing what you love! You can't expect to be happy by doing things that you don't enjoy. Sometimes you just need to take a load off and do things that make life worth living.
5. Clean Up Life
A person cannot be happy if his or her mind is full of regrets. Make sure that you eliminate as many regrets as you can because they will continue to haunt you.
6. Think of Others
If you are depressed, you are not alone. Around 300 million people suffer from depression worldwide in any period of six months. Yes, that many. People that are not happy usually feel that they are alone, and that only makes matters worst. Instead of thinking about how tragic your life is, think about how others feel that could have it ten times worst.
7. Go with the Flow
Follow and see where life takes you. Don't try to change things that were meant to be and don't frustrate over every little thing. Just live life.
8. Get Right Back Up
You can't expect to live a perfect life. For example, if you just lost your job, just get up and search for another. Think of life as a test of happiness, happiness being how well you can recover.
9. Be Grateful
Occasionally, you forget about all the things you should be happy for. If you realize how lucky you are to have been given life, health, family, and shelter, then you would realize that happiness can be found in even the smallest of things.
10. Focus on the Present
