Recently Ive Been Able To Identify A Core Belief Through

Recently Ive been able to identify a core belief through cbt "Im inferior to others" but Im not sure how to challenge such a thought? For example a belief "Im unlikable" Is easy to challenge because you can just think of instances where you were liked... and so forth... but how do I disprove being inferior? usually it evolves around my size and voice, not always being the most masculine. Thanks!
