Kanye West's confidence is no joke. He has an unflappable self belief which makes success become his reality. He gets a lot of stick for his narcissistic outbursts but incorporating his outlook into your life could change it for the better. If you take a leaf out of Kanye West's book we could all become more confident, successful and feel better about ourselves.
Everyone makes mistakes, even Kanye West, although we all make mistakes we need to remember to take the time to learn from them. Own them and move on.
Be more confident in yourself. You don't have to shout it from the rooftops but the more positive reinforcement you give yourself, the more positive you will feel. This can only be a good thing, if you believe that you can do it you can change things too. The more positivity you put out the more you will get back.
Another classic Kanye-ism, he is definitely writing history in the field of hip-hop, but this can be applied to our own lives too. If you keep yourself busy and enjoy your life you won't feel the need to document everything you are up to. Keep doing you and things will work out.
Everyone is an expert in something, you have the answers that someone is looking for be confident in yourself to share this knowledge and know that you are right. It may be intimidating to share but information is useless unless it it is shared.
Don't worry about what other people think of you Kanye has his share of haters but that has never stopped him from being himself.
Finally, believe you deserve more and let people (especially your boss) know that you deserve more too.
