slow down. think about each letter in each word as you're forming the letters with your pen.
in modern times hand writing is done rarely so the muscle memory is gone. when you slow down and write the common words and common letter combinations over and over again, you will get the muscle memory back and be able to write quickly again.
Slowing down is actually a really fair point. And Maybe doing some practice again.
it is really weird feeling in the beginning when you write slow. it feels like your brain is sooo slowww...
you can also practice with pangrams which include every letter in a sentence. the most well known being the quick brown fox jumps over the lazy dog.
