Of what are we talking? If I could have every single day consist of 50% sunny skies or have 100% sunny skies half of the days, I think I would chose the latter.
So, for me then, my answer would change depending on what we are talking about. But to be very honest, I am so glad I don’t have to make that choice, especially with the people in my life. I kind of like 100%.
Anything less than 100% is selling yourself short. I would take 100% 1% of the time just to be able to enjoy something that is 100% the absolute best. ;)
