Psychology is the science of behaviour & mind. This means that each discovery in psychology has potential of being relevant to our life, as human beings with mind & behaviour (no surprise there).
The best thing about this - some of these discoveries actually have implications in our everyday life, and can effect our focus, happiness, judgement, the way we effect others, and more - and those can be easily applied by us. Isn't this the most valuable knowledge you could own?

“You do not rise to the level of your goals. You fall to the level of your systems" - James Clear.

This lecture demonstrates academic theories and what we learned about dealing with lack of motivation; through creation of “systems” that maintains and provides that motivation over time.
