Feel At Home
If you play in club team matches or tournaments, try to visit any new locations before the actual match or if that is not possible, go as early as you can.
Visiting a new places sets up a particular frame of mind – a frame of mind where you know you are new and feel at a slight disadvantage.
By desensitizing yourself to the new surroundings you will be removing or reducing one potential worry from your list.
Knowing where the changing rooms, toilets, best places to warm up/cool down are will help you relax.
Learning to deal with new situations and places is all part of playing club team squash and those better able to feel at home will perform better.
