Happiness is not a simple goal ?
Change your soul (spirit) 
Practice mindfulness. Occupy your mind with positive thoughts and humming a tune, for happy effects on the mind and body. Focusing on your experiences in the present moment without judging them can help you become more compassionate to yourself and to others.

Meditate. Activities that promote meditation, including an extended, peaceful prayer, yoga etc... Developing your empathy muscles (helping others) will help you lead a happier life
Smile a little, hop, skip and sing in those moments, and they will not
slip so quietly through the cracks of memory. Say, "Thank you, so
much!"; perhaps, write thank you notes on Facebook, use text, email or
snail mail, appreciating people in a big way.
Look for the positive in all your experiences.
The old saying that you find what you look for is true start.
Because of this, make it a habit to actively seek out the positive in
any experience. It’s not only good for your overall happiness, it’s good
for your physical health, and boosts your immune system.
Don't give up on your ideas. "Try, fail often, get over it quickly,"
Share your gratitude with others. A word of thanks, even a brief one,
can make someone else feel appreciated. Sharing your gratitude with
others also helps you remember what you’re thankful for .
Let the good things sink in. It’s not enough to just note good things
when they happen. Really take the time to think about them and let those
experiences sink into your memory.
Begin by imagining yourself in the future, when you have gotten to where
you want to be. Pick a few goals and imagine that you have achieved
them. Make sure they’re personally meaningful, not external markers of
status.
Own yourself. accept and embrace your habits, your personality, the way you talk/look,
your voice -- everything that makes you “you.” Remember that you’re a
unique person who has value and is worthy of love and respect.
Don’t apologize for traits that are part of you, like your personality,
your voice, or habits. If there are traits you want to change, make sure
you’re doing it for you and not because you feel like someone
else has told you to. Make your decisions based on your values, not what
others have declared you “should” do or be.
Know your worth. Focus on making the best out of each goal you
have. Keep reinventing yourself/never settling back for long, while
applying yourself on any goals and opportunities you make.
Take deep breaths, and smile, even if there is nothing to smile about.
