Actually, one of the most important things I learned 'the hard way', is that you should actually 'learn not to learn' (i.e. really rest), and let go of any anxieties that may urge you to 'always be learning'. This insight improved my joy in life and tech, and also my focus and productivity, by much more then an approach of anxiously trying to be learning all the time.

Maybe for others things work differently, but generalizing into 'everyone should always be learning' seems too strong a claim to me.
