“The rich man plans for tomorrow… The poor man for today.”
Here we have metaphors for materialistic wealth. It’s not assumed the poor man is worse off, except in the mind of the materialistic person. The rich man is only concerned with money, materials, and worldly possessions. The poor man is only concerned with today, what they are doing now, and is more inclined to be spiritual rather than obsessed with possessions. To many of us, we would then want to mimic the rich man and only plan for tomorrow.
It is not necessarily bad to plan for tomorrow, but be mindful of your journey there and the importance of it. Do not be attached to expected results or destinations for that will only lead to inevitable suffering. Planning for today will not make you poor, even materialistically speaking. We need to plan for today and enjoy today for our spirits, and plan for tomorrow for our materialistic needs to be able to put food on the table and have shelter.
Moderation is key, we should not strive to be solely like the poor man or the rich man.
