Are you sure you are not seeking AFFIRMATION in the name of MOTIVATION?
Most people who claim to seek motivation actually seek affirmation and they probably aren't even aware of it on a conscious level.
Affirmation means feeling better about what you are. While affirmation is good in some cases like affirming work, affirming directionality etc, it is very harmful if applied to one's identity. Never affirm your identity, don't even acknowledge it.
True growth lies in doing stuff and not being stuff. Motivation is the only true path towards growth.
