There were subjects which I hated, either because I found them boring, the teachers were not inviting, or I just needed sleep. For instance, chemistry and national history are examples of them.
Many years later, I found myself in situations where I started to develop curiosity around those subjects, where I would wish to have properly learnt or attended those topics again.
I really had to think hard and I guess I seldom use it. I touch-type but somehow my body has learnt to use only the left hand for almost all the modifier keys no matter how many keys I have to press there. It’s actually a good idea that I only realise now that I should map that right shift for something else.
