what can makes you a credible person?

..hi.. for me, a credible person is someone who stand in his or her words.. What I mean is, a person is said to be credible if and when he/she says yes and do it or says no and stand with it.. A person without a changeable mind and with high integrity.. Included here also is well respected by people around him/her.. a person need not to be at the top to be respected.. A person is well respected if he/she shows respect to other people too.. I would also consider a person credible if he or she can make mature decisions and can face the consequences of his or her actions..
