A different entrance.

Feeling beautiful, despite circumstances are not accompanying for that. 

In some cases, you'll fall, but... EVERYBODY FALLS AND LOOK! THEY SEEMS TO BE HAPPY! 
WHY? How they fell and later they have known to get up?

8 hour sleeping
15 hour awake 
1 hour crying 

BUT (be careful with this word, is in capittal letter), the feel of sadness in some cases is necessary. It's necessary in order to realize the meaning of be that feel that everybody called "be happy". 

Be depressed is a mental disorder, feeling sad is not. 
It's a normal feel, as normal as breathing. 

So, if you want to feel sad,go on. Some time later, the intra emotion will change in you and you'll have the oportunity to experience 
Maybe better or maybe worst than the first one emotion, but an emotion anyway. 

Live. 

For everything else, play guitar (beautiful smile).
