Using Your Time Wisely

Which activities make you lose track of time?

I just realized something insightful today and a light went on. Next to reading and studying the Bible and being with God, the best use of my time is when I play my guitar. Music and practice seems is the best and most consuming use of time. What else can you
find that does that? Maybe art as well. It consumes time in a useful way, yet takes up most of my time without regrets! I can sit for hours making up new melodies and ideas.
