Back to the past

In my English class today we just talked about some different ways of communication. We discussed about email, postcards, calls, and blogs. Besides talking about the advantages and disadvantages of these tools, my teacher just told us how happy she was in the past, even without the internet. She told us that she collecting collected postcards from places all around the world. Also, different from our reality nowadays, she told us she used to send so many letters to her bother brother who still lives in the USA. While she was telling us her experiences, I was thinking that with our facilities ability to communicate with each other through the internet, we no longer care about letters or postcards. Surely we are grateful for this technology technological advantage, but I'd like to try this experience with letters. She talked passionately about it, saying that even though the it takes a long time is taken to get the letters and also the replies, the feeling of sending and receiving a letter or a postcard were unique and so good. Nowadays we just say and write things instantly, at the same time you take writing something you take deleting it (this phrase is confusing so I don't know what you are trying to say). Truly, letters are more than a memory.  They are a gift from a person you will never forget.
I just decided to start writing letters to some of my friends and maybe start a new hobby collecting postcards from different places. I am really excited for this. I like old habits traditions, especially when they are markable (not a word in English,  maybe use "personal"?). I wanna want to be able to maybe show my grandsons my letters and tell them I have sent and received some letters, at the same way my teacher just did.
Let's see how it's gonna going to be!

Overall, this is very good writing!  Only minor grammatical errors.  My corrections are to make the writing sound more natural, as if I was writing this.  My personal preference is to not use the word "just" when possible.   Most times, you can convey the same message without it.  Again, you're not wrong by using it.  Also, "wanna" and "gonna" are very informal and should not be used in formal writing.  I mainly use those words in text messages with friends.  Keep it up!!
