Is There a Roadwalker Barrier in Your Brain?

i almost have this battle in in my brain between wanting to be a, be better, or be better version of myself. And yet, i'm like scared of being better because i don't know what it's like. I think that what most of us are afraid of is the way that we will feel,. Most of us haven't created a safe place for ourselves? Mat you have any ideas on how, and how i might be able to, you know, confront that in my mind and address it?
