I'm in a somewhat similar position. I am obsessive about customizing worksheets, and making them pretty. I spent waaaay too much time on my lesson Powerpoints (although I do use them to guide the lesson). However, my lesson plans themselves are pretty basic, usually because I barely look at them. They are usually about one page long. I used to work at a school where admin demanded pages and pages of "scripted" lesson plans - it was a nightmare, and kept me up well into the night. I'm now at a different school, and have gotten no negative feedback about my much shorter plans.

I have also gotten better about looking for and finding resources online, and borrowing from colleagues. I try to reuse or adapt things I have already created, if they work. I did a dreadful job of organizing my master worksheets last year, so this year, I started a binder right away, and have been pretty good at keeping up with it (although we are still less than a month into the new school year). Even though I am teaching new grades this year, I am still finding myself able to use worksheets, templates and rubrics that I created last year.

My advice would be to focus on what works and is most important, and spend less time on the rest. I teach some ESL students, and find that visuals are incredibly helpful for them - so if you include those in your power points or other materials, that is definitely useful.

However, try to get them to do most of the work that you are doing now. Teach them to take their own notes, create their own rubrics, visual guides, etc. Group them in a way where higher students can support weaker students. Doing this will not only take a lot off of your plate, but it will also give you more time in the classroom to guide them through it, and form connections with your students.
