It's okay if you don't have time to find the best posts, that's y there's supposed to be other people on this platform reading other posts, not just you and bots. You don't have to vote on every good post. I see this belief that "I don't have time to sit and read through all the posts." Then one does not value enough what that person has to say on that post to take the time to read it. Going through content is not meant to be "skimmed" through, It's meant to be viewed and read.
I could just be in a guild and vote this post and "skim" through your post, but I value in what you have on your post to do that. Reading what you wrote and the comments is worth taking the time to read, even if I don't get to other great posts. There are other great curators that can catch the others. That does not mean we can catch them all but we don't need to believe that we have to vote on all great posts ourselves.
