A good leader is one who is open to suggestions. One who takes criticism objectively and not personally; considering them carefully and thoroughly. He is one who looks at his shortcomings as areas he can improve on and not shameful defects to deny and takes offense at when pointed out. He learns to adjust and accept changes even if it isn’t what he wants. He takes it willingly. He takes it humbly… seeking only what’s best for the project and not his glory.
The ones with the loudest voices aren’t always right nor are their ideas the best. Democracy allows us the freedom to speak our minds and to agree (or disagree) at any given moment. There’s a difference between suggestion and criticism- learn to differentiate.
