Opportunities

Should i be feeling happy or sad? Should i be smiling or crying?
By right, yeah initially, i should be feeling happy.
But somehow, because of something else, im not.
Yeah, i do know, those opportunities dont come often.
Opportunities are only for those who know how to cherish.
Maybe i didnt grab them in the past. And because of this, i've really regretted. Its like everytime when i said "no", i wished i didnt say it.
Everytime when i looked away, i wished i had stepped forward.
And really, everytime i rejected, i wished i had accepted.
Its a pity when you see those opportunities past by you, stop by others, and they make good use of it. And somehow you wish, you could be a little more daring, a little more courageous, and ask for them instead of them coming to you.
Maybe yes its true, if i want to succeed, i have to try all ways.
Not trying to be emo here, but im just trying to sort out my thinking.
I dont want myself to get so frustrated, get so sad everytime i think about it. In fact, i should be happy about today right? But maybe, because the issue has been on my mind for a really long time, and i hadnt find myself a solution to it.
But i cant change the past, i can only cherish the present, and not repeat those mistakes in the future. Yes, perhaps this is the best way to stay happy.
