Zeno is one of the ancient Stoic Philosophers. As such he is very practical and brief with his wisdom.
Jesus also eluded to this same point:

Matthew 6:26. It says, “Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they?”

Why then do we toil so much, plan, connive,practice and worry? What does nature know that we don’t ?
They know it’s all going to be alright. Just wake up, be grateful for the glory of the day and do your thing !
