I started with the immunization card I was issued when I was enrolled in school. I have a vaccination card from my home country (Mexico) and when my mother showed that, all that information was transfeered to a Texas immunization card.
I have the final report cards from kindergarten to middle school.
I have all my student ids issued in middle school and high school.
I have the final school transcript from my high school.
I have my high school diploma.
I have paperwork showing I took online community college classes.
I have certificates issued for being a volunteer at different childrens schools.
When I was able to afford my own apartment, I have the leases and bills under my name.
I tend to be OCD and have them organized by date and utility.
Thats all I got for now...
