Finally there are some things which are enjoyable to do. Anything pleasurable that we do regularly will reduce our general anxiety levels and make us feel more positive.
Boredom creates anxiety just as much as when unpleasant things happen or you become afraid of something. Therefore having interests which absorb you is the single easiest step to take to beat anxiety habits.
In order to feel anxious we need to think about anxiety provoking things. If we are totally engrossed in doing something enjoyable, by definition, we don't have headspace for those negative thoughts - hence no anxiety.
I have just listed some possibilities below. There are hundreds of others.
You might be a gardener, draw, do colouring, bake cakes, sew, knit, crochet, train your dog, take photographs, write poems, even build a website. There are just so many wonderful things to do that are preferable to feeling anxious.
