Try to use each hour of your time in its highest and best use.

If it's a special / rare hour, use it for special / rare things.

For example, if you're on a short trip to Dublin and your coworkers ask you to go to the pub after work, even if you're tired, you should go!

As another example, if you're based in Dublin and go to the pub with your coworkers multiple times a week, then maybe it is better to every so often just stay at home with your partner and watch Netflix.
