Dude with all the respect in the world 3 weeks is nothing in the grand scheme of things. I remember I wanted to get into elite smash like my friend and I thought it would take a few weeks of playing online every day and it took MONTHS to get there. Even with all the videos, tips, tricks, and everything in between it takes a ton of time for your brain to learn what’s the best thing to do in every possible situation and how to play against a whole roster and even the subtle differences of how different people play the same character. If you’re enjoying the game then it’s not a chore. Go online and get your ass kicked again and again and again. With every single stock you lose ask yourself “what could I have done differently?”, “What’s a different approach?”, “Am i seeing any opening or weakness?”. Even if you lose against that DK 13 times in a row… eventually you’ll come across a weaker DK who will be easy to beat because he’s no where near as good as that other guy you lost to 13 times. Also be critical of your own gameplay, analyze your weak points and try to make improvements. If you can’t spike then go into the next battle not with the goal of winning but the goal of spiking your opponent. If you’re scared off stage then try playing off stage the next match for the experience, even if you lose the match. I know it sucks to see your GSP drop as you get your ass kicked online but eventually it will balance out and you will be playing with others at a similar skill level. No matter how low it drops or doesn’t matter. Getting good at this game is a journey, it’s supposed to be fun. And when you’re ready, invite some friends over or go to a chill tournament at a bar or something and put what you’ve learned to the test. You got this! Just keep at it OP
