should I shorten the story I'm writing to make it an easier read?

I agree with David and Speed. You don't need to worry about length when you're just getting all your thoughts down. It's a draft. After you distance yourself from your work, it'll be a lot easier to see where you should trim stuff down. You're not as attached to all the feelings and ideas you wanted to convey then. You are more focused on what's actually coming across to you as a reader.

That distance is very important though. Try to give yourself at least a few weeks or months away from your work before you begin serious editing. I can almost guarantee that you'll have plenty of unnecessary "fat" that you need to trim down. It's not a sign of being a bad writer. It's just that good writing is concise. This doesn't mean that you should have short scenes, paragraphs, sentences, etc. It means that everything is only as long as it needs to be and no longer. It means your scenes that aren't adding anything significant to the story (or disrupting the pace of the story) are taken out or modified.

I had an English teacher who talked about the publishing business once and he mentioned cutting about 25% of the original draft out. Kind of a frightening number, but once you start evaluating your work and pinpointing where the fat is—it's not as bad as it seems. Before you start editing, just jot down your draft's original word count and see how much falls off each time you edit. It's personally not too hard for me to shave off a couple hundred words when I do some light editing. If you're having trouble getting rid of stuff, get some feedback from people and do more trimming on your next edits.

A painful part of writing can be editing out what doesn't belong in the final draft. It's a good idea to overwrite your first draft, but the second and third drafts need to be carved down until there is nothing left but the story your telling without a lot of needless fluff.

My suggestion is to finish the story first and then use your first revision to see where you can cut something. Most authors tend to be wordy in their first draft, so if you're in that category, you might find that your novel will have just the right length after revising, even without doing any major plot tweaks to lower the word count.

A boring book is bad for many reasons, but length is not one of them. A good story is well constructed without extraneous characters or elements, and doesn't wander much. 75,000 words is considered a short novel, anything under that is a novella. Sometimes a short story is more effective than a novel, but good short stories are very hard to write. It's all up to you.

30,000 is about novella length. Publishers do not, on the whole, publish novellas. You have another 50,000 words to go before you need to start worrying about length. But if it's boring it won't matter how short it is.

You could divide the story into segments and publish the segments (like Star Wars) over a period of time instead of all at once. The trick is to hook your readers to keep them wanting more.

First drafts always are too long. The revisions are what's done to take out the padding, the fluff, the irrelevant, basically anything that does not move the story forward.
