There's no point in consistently worrying about everything.
Que sera sera, whatever will be, will be.
It will be as it is meant to be. You can rant and rave, scream and cry, throw things, do anything that makes you feel better, but until it is time.... nothing will happen. You cannot control it, control is an illusion.
You usually dig a bigger hole by fighting what is... you can't change the way things are at this moment, they already are. So, if you find yourself in some predicament, and feel the anger/indignation/resentment or which ever negative emotion is uppermost in your mind, rising within you... what do you do?
You need to look at the situation, see what is going on, take it all in, and either change it or accept it. If you are able to change it, then by all means change it; but if you cannot; your only choice is to accept it and carry on. It is what it is.
If you are worrying that something may happen, you are wasting your time.... most things you worry about will never happen anyway. You cannot force anything to happen, so just go with the flow, it will happen or it will not. You need to trust that whichever way it goes, it is for the best. Just breathe. Live in the moment, do your life, enjoy yourself.

Be calm, be at peace...the journey has started and you are in charge.
