What do you need to be happy everyday of your life?

Hi everyone who will read this message! :-)

Since few months... I have not been able to be happy for a long time...
I went in beautiful places, spent great times with very good friends, did stuff that I love like rock climbing, snowboarding, I listen to the music that I love, I played on my guitar.... But at the end of the day, when I am back home... I am kind of feeling sad...

When I was young I was afraid to try stuff or experiment new stuff because I was thinking that you cannot miss something that you don't know about... I wanted to be happy by myself with the fewer things possible... I did not want to be addicted to anything so I could be happy with nothing... It was like that for stupid stuff (never sleep with a pillow to be sure to be able to sleep in every situation! hahaha) to more serious stuff ( I was afraid about going into a relationship with someone because I knew that I would miss it so much if something happen...)... Is that stupid?
I still like the idea to be able to be happy with nothing... Simply happiness! But...
But if you don't try anything you won't change... Maybe you don't want to change... but if you don't change you won't improve yourself... Do you think that you are great enough that you don't need to change?
I don't think so!
Finally, after many years of happiness by myself... I felt kind of stupid because there are a lot of things to do on earth and I did not know anything... Is not that stupid?
So I started to change! :-)
Now...
I still sleep with no pillow... hahaha... But I tried love... I felt in love with someone and this one loved me.... And love is the strongest sensation I've ever tried and had...
Since few months, the love left me... I feel like I am not able to be fully happy...
It is like if I lost my wings...
I am still able to breath, to talk, to run, to laugh, to eat... But I feel that I cannot fly anymore....

So... What do you need to be happy? To be happy everyday of your life?
Nothing? (you need nothing or nothing make you happy? ;-) )
Your iPhone? ;-)
To love someone?
To be loved?
To be famous?
To have a lot of money?
To live close to your parent's place?
To have 500 friends on Facebook?
To be in love?
To live in a big city, or in the country side?
To be with someone who wants to conquer the world?

These days, and in France in particular, People look to never be happy and this makes me crazy!
Are we that in demand?
Looks like for a lot of people, when they have what they want, they want more, better, again and again... looks like it's never good enough.... looks like they are NEVER happy with what they have...

Ok... On this message I say that I am not happy either.... But the only thing that I want is love...

As nothing has made me happier than when I was in love and be loved... This should be enough to be fully happy... no?
Everything more should be only bonus... no?

Can you be happy without the love of a GF or BF?
Or is only the love of your friends and family is enough for you?

What do you think about?
