Do you have one line of text or paragraphs, mulitple pages???? Maybe you have a rough edged font, along with a font that is free and has techncial issues and an abundance of extra paths. Please post a screen shot of your artwork in preview and outline mode. You have images but we know nothing about them to be able to advise. Knowing what font you used could be helpful also.
14mb is large for an illustrator file, do a save as and turn off pdf comptaible unless you need to embed this into InDesign or After effects. Any placed images save as .psd and link to them and don't embed.
Maybe you do not need to outline, we do not know enough about why you are outlining to advise other methods such as embedding font into pdf.
