You need to be your own best friend.
It is important to learn to listen to the signals your body sends and act on them. Just as a sprinter needs to recover between sprints, you also need to make sure to rest and relax between intense study periods.
It is also a good idea to make a list of what gives you energy and what drains you of energy. This way, you can better allocate time to the things that give you energy, so you don’t end up completely “drained.”
This could be, for example, going for a walk, listening to music, exercising and practicing mindfulness, seeing friends – or just relaxing on the sofa.
When we recover and do things that give us energy, we also optimize our learning and development, which, for example, benefits exam preparation.
