From Psychology Today: "The idea of eating the frog refers to doing the task you're least motivated to do first. This can be a great strategy, but if you're feeling low, trying to do your hardest task first can lead to you not getting out of bed. Ask yourself, "What's the most productive task that is within my capacity right now?" For example, if you'd like to go for a run but you can't get yourself to do that, then going for a walk is better than staying in bed."
Sometimes it is difficult to get motivated. Especially during the summer. One thing we've always heard is to "eat the frog". This article from Psychology Today discusses why that might not always be the best strategy.
