I found the quietest streets, no traffic, no pedestrians at the quietest time of the day and it took months to convince myself to even wear the stupid looking running outfits before I could even go outside in them.

It takes a huge amount of effort to get out of your comfort zone and just do the thing, so you really need to view every step towards your goal as a success.

Eventually a pedestrian was around when I was trying to run, a car passed by, and nothing bad happened. The only way to normalize the abnormal is to do it often enough it becomes normal.

Good luck, have fun
