People often confuse relaxation with recreation. However, if hobbies or other activities – including exercise – become excessive, and make you feel even more driven or pressurised, they cease to be relaxing. If you are already exhausted in daily life, trying to relax by doing even more is not the answer.
The first thing is to become more relaxed in daily life and not to waste energy on things that don't require it; such as fidgeting impatiently while you wait for the kettle to boil, or getting impatient with the photocopier. Instead take the opportunity for a few moments of calm.
The second is to learn some breathing and relaxation techniques.
