IMHO

It’s so much better to have an excess of ideas than to hit a creative block.

As to too little time; don’t waste more time fretting, just pick some ideas and go with them.

Yeah... it sucks that you don't have time for everything, but it's awesome that you have an excess of ideas

I did a short in Chapter Seventeen that deals with this issue, standing in a desert in darkness, the dunes making darker shadows towards the bottom, then daytime. I used a winged race that look like blue eyed brown haired wider chested humans with Falcon's wings called a 'Vegan'.

in retrospect, never trash any idea even a bad drawing where the lines are not perfect (you can always use a light table to trace the lines you want to use), between the age of 27 to 35 I was the most prolific, I developed a new RPG, but then life got in the way and I had to put it off until now. whatever you create don't destroy it.

I found out everybody are the most prolific at doing something between 27 and 35 later on.

Save all you old work; in time you will forget what you were trying to do and see it again with fresh eyes, or you might have answered whatever block you had then with something you've done since to finally finish it. I destroyed all my late 60s and 70s porn including most of the 80s. There was no one to share it with, I had to wait until Furry was invented in 1996. You I suspect were born later, than I was.

Save all your work including the rejects.
