Commitment
Commitment is being dedicated to a cause, keeping a promise, or the loyalty you keep to someone or something.
I believe in order to make a strong commitment you have to be loyal and really mean it because if you don't you're going to fail, break your promise and that's going to affect others, not just you.
Loyalty
Loyalty is the act of being loyal to someone or something, also a strong act of supporting another.
Loyalty is something important that we all seek for in a friend or significant other. If there isn't loyalty in a friendship or relationship it won't work out. I usually look for a friend that will be there to help me when I need them or a shoulder to cry on. Someone that will never talk behind my back. Someone who if they overhear someone talking wrong about me, they will stand up for me. Someone who won't pretend to not know who I am if we see each other outside of class.
