Looks like the hustle of life is a simple representation of what we were taught in Economics about "human wants being insatiable".
We always want more because what we have and where we're at is never enough.
We're so preoccupied with getting what we don't have, that we lose sight of fully utilising what we have received at the moment.
The hustle is sweet, and it's cool to go after what we want. But I guess it's also important to recognise and enjoy the blessings we've already received – blessings we didn't have to work for.
"… do not be so preoccupied with getting, so you can respond to God's giving." Matthew 6:31 (MSG).
