We were made to use our hands.
It's easy to get bogged down with life's small tasks and details. It's also easy to "Just get by". With living in the reality of "just getting by", it's very easy to fall prey to unhealthy thoughts, habits, and relationships.
So what's the alternative?
Use your hands well. To use our hands means to have a purpose, a direction in our lives. Doing hard things that creates good in the wold refuses to live into a "Just getting by" mentality. Doing significant work requires dedication, commitment, and ultimately consistency. Through filling your mind with purposeful, healthy thoughts, it's much easier to not give into unhealthy ones.
