"the capacity to have an effect on the character, development, or behavior of someone or something, or the effect itself."

Influence
I made this site to recognize 20 individuals who have had a substantial influence in my life
(since that's how many stamps came in the Keith Haring Love pack from USPS)
From laughs and cries, hugs and fights, inside jokes and arguments - each one of you has developed so many unique memories with me, with hopefully many more to come.
You have received your letter because in one way or another, you played a massive role in influencing who I am today.
For that, I must say:
Thank you.
I wouldn't be the same without you.
