Yes, life is uncontrollable. If that gonna answer your question!
So what we actually do in our life? Basically influence. For whatever we do definately will affect the cause in the future. What is now is for the future. This is when the quote "think before you act" applies. Our action now is gonna determined what is gonna ahead. So mind your steps if you don't want to bang into something unwanted. It's all up to us.
So who says that life is uncontrollable?
If you wanna blame others for whatever not-so-good thing happened to you, think again. What have you done that brought those to happen? What action of yours that influenced those? Any measure taken to avoid them?
So stop complaining. Stop the tears. Stop wetting up your cheeck. Life is for us to live, so live it to the fullest.
Yes, you can't control others. So start to control the one you could; yourself. Life is unpredictable? Yes, it is. Well, that's the beauty of life isn't it? And let us keep it that wat; misterious..
