...then at some level, you feel undervalued.
Not personally or professionally, as much as spiritually insignificant.
The solution is NOT to consciously commit to less; it's learning how to see yourself better.
Currently, the problem is that when you look at yourself (self-image), you don't entirely like what you see / who you are, and you believe that doing more will fill your void.
It won't; it can't, it's a trap!
To be blunt, you've confused and now believe that some painful experience(s) from your past is who you are.
You've mistaken your Experiences for your Identity; this is what I call an identity crisis!
The ONLY solution is to contemplate who you are apart from the painful, ill-defining, and degrading experiences of your past--action will not help you here; it will only make matters worse.
Premature action is a desperate attempt to become worthy, while contemplation is a willingness to embrace your inherent worthiness.
Once you recognize your foundational goodness/enoughness, overcommitting will not make sense.
