Nice Guy Syndrome: Things you should Fix before it's too late - Being a nice guy and pretending to be a nice guy or aka people pleaser are two different things. The qualities of a nice guy indicate a positive vibe, non-confrontational, honest, loyal, supportive, respectful, courteous, etc. for the negative person who is a people pleaser is just unassertive, clever, dubious, and the one who does not express his true feelings, etc.
