Defining success

Investigating the emotion I’m looking to feel by reaching my goal, I’ve uncovered that I want to feel successful.
When I ask myself “what does that even mean?”,  I can go to my body and try to identify the sensations.
Embracing the concept that “‘there’ is not better than ‘here'”, there is an element of me thinking that if I don’t reach my goals, I’m not successful. Black and white thinking perhaps? So then I move to defining what success means to me. Part of it is getting ‘there’. Can you help me unravel this please? Could it be that leaning into ‘unsuccessful’ on the other end of the spectrum, is something I want to allow? (Maybe it’s my brain disguising or defining failure as ‘unsuccessful’.)
