Archive is an good way to trace you life with the work you have created.its like a digital footprint. the speaker in this video talk about how he has a blog for his son and puts up family pictures.he says this because he doesnt have any pics of him as a child because his parent didnt take any so that’s one reason he say that we have to work on this. Also this archiving will help you to race back and make you realize of how you did it.
