I can think of ten unique usages and definitions for the word dig (and it’s derivatives). Merriam Webster claims that ‘to break up, turn or loosen (earth) with an implement’ was the original definition and has been used since the 12th century. It’s so strange that dig, a simple action verb, demands such an array of metaphorical usages in common language.
Digging is an extraordinarily tangible and time consuming task. Hard, repetitive physical labor allows the mind to dig for meaning, seeking justification for the work.
Identifying intention and goal setting are behaviors that are invaluable. It is so much easier to dig in your heels and tuck your ears when there is a light at the end of the tunnel. Try to keep the goal in sight.
It feels like life is like digging a hole to the center of the earth. We pick a spot and keep working. Sometimes the earth is soft and the going is easy. Sometimes the walls collapse completely. All we can do is find work we dig and give everything we got to create the cleanest, biggest pit we can.
