We're not all serious when it comes to yoga. If any action doesn't also give us pleasure, then we have to reevaluate why we do what we do. The same thinking goes with our yoga practice.
So, even though we all want to reach a certain goal while we're practicing yoga, we also allow ourselves leeway to falter. It's not a big deal. We practice, we do our best and we let go.
Have fun in yoga!
