I haven’t seen your dev skills or youtube skills but psychology-wise, I have.
Would if I could, you’d skip all the BS, get to a part-time paying position and learn psychology ‘facts’ as-needed on the job. You’re a clear thinker; that’s all I’d need to see. You can come up with your own theories while helping people. You don’t need anybody else’s unless you want to ’cause your head is clear.
[ie – you see through the BS and know what’s needed]
