I agree.

Very important note - not many people realize this but being productive also does not mean mindless busy tasks. We need to do work that are meaningful to ourselves which allow growth that are beyond our comfort zone.

It’s difficult challenge many of us are facing but the reward is huge as that is what you will remember when you look back on your life. :)
