Remember, picking up the light arrows build on each other. We cannot pick up the second arrow without picking up the first one. And by the time we pick up the seventh Light arrow, we have picked up the other six before it.
The 3rd Light Arrow, which builds on having self-awareness and self-appreciation, is Self-Acceptance. Choosing Self-Acceptance opens the door for our self-esteem to grow. It allows us to ask ourselves at any moment or in any situation whether we did or are doing the best we can do based on what we knew/know.
Remember the 3rd dark arrow is judgements. Often times we look backwards in time and judge our behavior or performance based on what we now know. Or we judge and put others down so we can feel better.
Knowing deep within yourself that you have done the best you could, given what you knew at the time, provides a moment to take a deep breath, silence the internal pretender voices, and break the pattern of judging self, life, and others.
