Here is my interpretation of what this means:
Think Less: You procrastinate less and this eases the stress that hinders our positive view of life.
Feel More: Our instincts tend to lead us in the right direction. We go in the wrong direction typically because we defy those instincts.
Frown Less: Hopefully we frown less because we are happier but if not, then frown less so you don’t admit emotional defeat knowing that you can turn that frown upside down (there is hope).
Smile More: When we smile more because of the positives we experience, we focus on and as a result magnify those positives.
Talk Less and Listen More: We learn more when we listen because either we change or reinforce our positions. If there is a reason to change, then be open to it and if our ideals are reinforced, then we must be thankful for the wisdom we have.
Judge Less: We do not know a person’s heart nor “their” perspective on their situation. People do not know ours so we shouldn’t judge.
Accept More: Don’t fixate on what you cannot fix; accept it and move on.
Watch Less and Do More: Again, don’t fixate. If you can fix it, then do! The opportunity to “do” may pass you by if you don’t.
Complain Less and Appreciate More: Much like “frowning less and smiling more”, we must focus on the positives.
Fear Less and Love More: In this context, fearing less and loving more is about focusing on the positive “what ifs?” as opposed to the negative ones. There is always a possible downside to things but that should not keep us from exploring with a view to the potential positives. We should look at the situation, weigh the two, and then make an informed decision. If the negative results, remember, “Accept More”!
