“Do the best you can until you know better. Then when you know better, do better.” 

This quote comes from Maya Angelou. It reminds us that it’s only when we know better that we’re able to do better. Until then, we can only do the best we can with what we know at the moment. Therefore, there’s no point in beating ourselves up for our shortcomings and failures if we were doing the best we could based on what we knew. We can only learn from them and do things differently.
