Show Appreciation For Everything
Give a gift to everyone you receive something from.
Buy a bunch of chocolate bars for example, that you can give as a small token to anyone from whom you have received something; advice, help, anything of any sort, to show your immediate gratitude.
This will improve your sense of appreciation for everyone and everything, which results in stronger self-esteem.
