This is saying,to me, that you should use your time wisely because if you just sleep all the time or never do anything, then your life will be over before you know it and there will be many opportunities left that you wanted to do that you will never get to. Personally, i want to do all that I can in life and live life and die with no regrets.
"Be ashamed to catch yourself idle."
This proverb and the one above are like to peas in a pod. If you ever find that you have a lot of free time, you should really try your best to get out and be active, accomplish tasks and opportunities. It's okay to have a bit of down time, but you shouldn't turn into a hermit.
