For the second technique...
Talk to yourself with respect. Look at yourself everyday in the mirror and instead of thinking "I hate myself" say "I love myself". Keep in mind to not get TOO confident because that can affect/bother others. If you catch yourself saying something negative about yourself please do me a favor say to yourself "I love myself". It may take some practice to believe it yourself depending your self-esteem. If you can't bring yourself to say something positive don't worry just say "The Librarian is my friend and she loves me so I should too!".
