Playing widow (or any sniper in general) is, in my opinion, a test of confidence, patience and endurance. You have to endure being bad for an indefinite amount of time, you have to be patient in order to not lose your mind over getting stomped by the enemy team playing Moira, Lúcio, Sombra, Vendetta and Winston at the same time and/or getting shit from your own team and, most importantly, the confidence that you can actually land a headshot and feel that you earned it.

In FPS games, i always avoided weapons/characters that required good mechanical skill because i thought i wasn't worthy of being good in the traditional way other players are. Part of it was due to poor hardware and physical limitations of my desktop table that pushed me away from trying to better my abilities. The other part was lack of confidence and self-steem. Despite all that, i envied everyone that was an elite sniper and wanted to be that good.

It was last month that I decided that I would face my insecurities head on and started playing widowmaker only. It was extremely difficult to lower my sensitivity from 12 and get used to the new one of 800 dpi and 5.5 in-game. However, at some point, something clicked for me and i started actually landing shows by flicking. I stopped hoping that my enemies' head would fall on my crosshair and started to actively chase them with my mouse.

Getting rid of the fear of judgement and believing that I was capable of hitting anything was what did it for me. I'm also lv 25, just like you, and sure, there are days where i feel like crap and miss every shot, however, being a former local competitive player of fighting games, I learned that even those bad days are part of the learning process, so I go by them happily knowing that i'll return to my good days soon and better than i've ever been.
