What's funny is that I have only worked for the big tech companies since I graduated and I know how to do all the backend stuff really well and thus I can do it in a few weeks for my side projects. However, the fronted code kills me and I keep stalling and getting confused on my new projects trying to figure out all the js/html/css to make it look really good for normal users...
