Think about it, GOD gave you brain, hands, legs, kidney, ears etc so that you can use it to your advantage. To live as you wish. If you wish bad for yourself, your body or whatever then you'll get what you wanted all along!
If you wish your life to be in bliss as if you're in heaven then of course you can make it to be. Of course, once in a while there's adversity that you have to pass through to reach the other side. Everybody have to go through it. Sometime, it seems you can't do anything about bad things that seems to happen but hey, whatever you set out your mind to do or achieve, sooner or later you'll achieve it. No matter what!
Yes, no matter what. Say you can and you'll can...be happy.
Have a nice day!
