Self doubt

Pace... speed... tempo... velocity... whatever, you name it!
It all mean the same in one thing: in Life.

Old and wiser folks said, everybody had their own pace, chooses their own road, and walking their own steps. But, as we are younger and foolish person, we cant help ourselves to stop looking at other (now is the time to said, the grass always greener in the other garden).
I see people have come so far, accomplished so much, and done so many things that makes me in my gloomy day, feels like loser.
There are many things I want to do, but there are many limitation. I know I shouldn't give up, and I'm not giving up. I guess I'm postpone it, or putting it aside, and concentrate on things that urgent.
But then, it grew self-doubt in my mind, can I do it? can get what I want?
the thing is, in my life, I rarely get what I want (beside books, that's why I like books, they never fail me), and I cannot be like some people who just go and chase their dreams and leave everything behind.
I can't leave everything behind...
I can't walk away and not turning back...
I don't even sure I can walk away...

and so I stay, and dwell in self-doubt on should I be a responsible family member, or go for experiences and adventure...

me, in my gloomy day
