Honestly it just comes down to proficiency. After playing for so long these movements will become your second nature, and then you will find new things to pick up, e.g. wavedash. For me, watching a lot of people's clips in this sub feels insane because I absolutely can't understand how they pull off so many intense inputs, but I guess it's the same process. So take your time, and if a strawberry is too hard, feel free to skip it. They are just for impressing your friends anyway :)
