if you worry about it happening then it is going too so dont worry about it what is going to happen and just enjoy the day as it comes and when things go wrong just suck it up and move on we all have bad days from time to time and there is not much we can do about it but move on and make the best of it and have fun dont let any one get you down for it enjoy life it dont last long
Just adopt my old mum's motto :
You die if you worry
You die if you don't
- so why worry ?
