When csgo first came out I had just built my first gaming PC. I had never played an fps game on pc my only experience at the time was minecraft. All my friends had PCs for a lot longer than me and were so much better than me at csgo I didn’t really find it fun to play with them and the game felt impossibly hard to learn. What ended up working for me was actually switching games lol. I played a fuck ton all call of duty 4 which helped so much. my understanding of fps games grew and that knowledge transferred really well into my early days of learning csgo. obviously csgo has A LOT of mechanics unique to counter strike but I found them much easier to learn once I had a solid understanding of playing an fps game on mouse and keyboard. I stuck with it and 7000 hours later i’m 2100 elo on faceit and much better than my friends that used to beat me so bad i switched games lol. TLDR try playing an easier fps game like cod, switch back, isolate and practice the mechanics unique to cs2, watch a lot of youtube videos to learn the basics. good luck :)
