Being a high achiever with impressive external accomplishments doesn't necessarily translate into fulfilment and true self-worth.
The lack of self-love or low self-esteem is central to any mental or emotional distress that makes us unhappy. We feel separated from the true Self (the Source) whether we are aware of it or not.
You are far greater than your ego, but your ego does get in the way. Not that your ego is the enemy. The ego helps you to realise your greatness and break the illusion of separation.
Becoming aware that "something is missing" is a developmental stage (self-actualisation) that comes when the lower-level needs have been met. When you reach this level of development, you have to turn inwards for further development. You have to connect with your true Self, which means you are dissolving your ego.
Reaching an outcome is one thing, but if you don't feel fulfilled, you might be on the wrong path that will not lead you towards the next level of growth.
According to the existential theoretical framework, your whole purpose in life is to know your greatness or self-transcendence. Your passion, desires, and achievements guide your journey towards your greatness.
Internal satisfaction triumphs over achievements. Focusing on busy work may prevent you from having true joy and fulfilment of work.
Your reality starts with self-love. You feel the lack of love because you feel separated from your true Self. You can realise your greatness by simply loving yourself.
