Doesn’t that kind of sum this mentality up? “Show off”. All approval is dependent on surface appearance and must comes from outside you.
That is just so depressing and disconnected.
Your body is you. Your connection with it is part of your consciousness. So, to detach from that, to seek to view it only from the outside is peculiar and unedifying, though thoroughly normalized.
Whether my body feels at its best or worst, I approve, respect, like it. Other people’s approval is fine, but it cannot replace that.
