A little bit of context 

I was asked to write about important things about me that I think I would like my great-grandchildren should know about me. 

Thank you, in advance.  

To my great-grandchildren 
For the following lines, I'll be writing a little bit about me. If you may find some words or collocations somewhat old-fashioned this is not because it's you great-grandmother writing, it's just how we put words together at the beginning of the 2000s. As a matter of fact, I'm really cool, I'm always tuned in and probably way cooler than your friends' great-grandmother. Just saying.  
Speaking of which, I'm not just a pretty face that you see in old pictures. I am someone who grew up in a small city, in a very religious family. The first person in the family ever enrolled in university, who by the age of 7, decided that was going to law school, so that I could wipe all injustice off the face of the earth, who, also, later found out that that was not realistic possible, but went to law school anyway. Someone who is generally happy but able to put on a grumpy face all of sudden for apparent no reason, also, known for speaking loudly and being reckless and at the same time an unassuming woman, organized and serious.     
Despite what I said, what I really want you to know is that I once was young and had dreams as you. That I went through life for a period, fearful about a future I didn't know how it was about to unfold. That in terms of personality I have lost it and found it so many times that I can't even tell how many, and each time I recovered it, I struggled to figure myself out even though I know myself as anybody else does. The key here is to understand that this is all right, it's part of the journey, and you will be fine, although it might take a while to convince yourselves of that.
