Here is a list of pursuits aside from bird-watching that are potent means of psychological hygiene:
- Embroidering;
- Knitting;
- Fishing;
- Hunting;
- Berry-picking;
- Mushroom-gathering;
- Walking in the woods (but without any music);
- Puzzles (but they’ve got to be real puzzles, not the online ones);
- Non-competitive chess (again, not online);
- Drumming;
- Stringing beads (non-commercially);
- Singing in a choir (again, not for money. All of this has to be done as a hobby and not for a living);
- Staring into a fire;
- Making a herbarium;
- Attending religious services.
And the cheapest of all: day-dreaming. This is a great and very accessible source of energy.
If you are gravitating towards any of these activities, this means you have very good instincts and a fair degree of psychological health. If not, try to explore some of them to see if you might like at least one.
