If you keep doing the same things over and over again, you're not going to learn anything new.
Hence, once in a while, you need to break your usual routine and delve into some foreign territory.
Whether you simply take a different route to work or decide to embark on a whole new hobby altogether, your day will be a lot more interesting the more you alter your usual method of doing things.
Flexibility is something you have to exercise once in a while, or else you get stuck in a rut.
Once you get into a fixed way of living,
it becomes difficult to change!
Once you stick to one way of learning,
it becomes dry to learn, and
learning becomes difficult!
