I always try to look for the positive, in people and in situations, and to focus on those rather than the negative aspects. Of course sometimes there doesn’t seem to be a positive aspect, it all looks bleak, in which case I try to accept that everything happens for a reason and although I can’t see it right now, some time way down the line I’ll look back and say “ohhhh so THAT’S why that had to happen!”
And if it is beyond my control, then all I can do is accept that and sit back and wait to see how things unfold and watch for the opportunity to take some control back again.
