Sometimes our hands are overly occupied trying to get a hold on something that's not within our reach; sometimes we are just wasting our time looking to control something that we really have no power of.

Life consists of so many variables, but there's really only one of which we can control: our very own selves.
It can be very vulnerable, it can be really strong, but the only thing that can protect it is our willingness to accept that not everything is in our hands, not every decision is ours, and those what ifs could never change the unchangeable.

We have to accept that there is a greater force keeping our lives running, by whatever name we call it; and we are not the omnipotent, nor the omniscience.
Nevertheless, however little we can do, we must do to make it matter. We control ourselves, and we'd better be bloody good at it.
