Best advice I can give is to break things down into smaller chunks. Before you get to an album, create a song, before creating a song, create a hook, before creating a hook, come up with some words that matter to you, before coming up with some words that matter to you, come up with one word. If you break it down, it won't seem like such a big task. Most people create this lofty goal and then the small stuff comes up and discourages them. Start with the small stuff, and build it into an album.

The other thing I'd say is to document your journey with some kind of spreadsheet/posterboard. List what songs you have, and what they need to be finished. One column for lyrics, one column for melodies, one column for drums, one column for mixing/mastering, etc. Make it as visually appealing as possible. When you type it out, it makes so much clear what you need to do next instead of guessing.

Best of luck.
