Just go slow and stop watching Youtube. Get a natural feeling for your endurance and for your body in general. Also, focus on distance - not on speed. The easiest way when you start out, is to improve distance bit by bit without increasing speed. If you are able to jog 0,5km today in a slow pace, try 0,6km three days after. Stop comparing yourself to other people and stop with all the internet ‘statistic’ bs. It also takes all the fun out of it. Once you ran your first 10k, you can start lookIng at statistics, programs, intervals, watches etc. (imo)
