Self-esteem: Are you warm-blooded or cold-blooded?

Cold-blooded people rely on their surroundings for 'temperature regulation' (Photo: Shutterstock)

I recently watched a video by one of my favourite YouTubers, Shallon Lester where she tried to explain the use of internal and external validation as the source of our self-esteem. She termed those who sought internal validation as warm-blooded and those who sought external validation as cold-blooded. 

In biology class, we were taught that warm-blooded creatures are able to regulate their own body temperature, whereas cold-blooded animals rely on their surroundings for temperature regulation.
