There are things we fill our lives with that are a range of sizes: from big, toddler-sized bricks, all the way down to the tiniest 1x1 circle brick. (You know, the ones we always vacuum up first?) All these pieces all actually fit together though, even though at first glance they don’t look like they do.
Think of your productivity in life as the structure you build with the bricks. You have a maximum size that you can make it (we all have 24 hours). But within that size constraint, you can have as many pieces as you want.
