Spending breaths

What can I do in life? A question to ask where my breaths have been spent this week.

• Helping to check two essays for a friend
• Getting back the assignment written a month ago
• Working out
• Being examined in a physical exam

• Playing guitar for practice
• Studying in a group
• Practising patient-interviewing
• Doing calculations in inverse square and exponential equations
• Chilling, meaning thinking, talking about, and doing nothing

Sometimes - actually sometimes it's many times - I ask what's worthwhile doing.

I'm not going to be alive forever. What's worth spending my breath on?

So many things are a waste of time. So what's not a waste?
(In case you're shading this to find an answer, haven't got a definite one, but I'm still thinking about it.)
