What is the meaning of this sentence?

I take it to be a rhetorical question meaning the writer is very busy. I doubt there is any deep philosopical hidden away in there.

Thanks for your answer!

Is it possible that I am so busy (working) that I no longer have time to enjoy (life)?

Actually , this sentence is from my text book. Maybe the "working"and"life" are better.And I think it is easier to understand the meaning. Thank you very much!
