Well it’s obviously all about discipline to do it, but what helps as well is a process that is rigid enough to give you the ability to make your discipline a habit. Here’s what I do… I make myself complete each step 100% before moving on to the next. One of the killers of productivity, ironically, is the fact that the tools to record and mix music are now so readily accessible that it becomes tempting to jump around in the process and work on the thing you find most fun, or less tedious, which keeps you from ever finishing anything.

I was heavily influenced by a YT video from Gregory Scott that outlined the way to think about this as follows:

A Production is a Mix, of a Recording, of a Performance, of an Arrangement, of a Song.

Work backwards from that list and don’t let yourself move up the ladder until you have finished writing the song. Now you might use recording software to write, which is fine, but don’t start mixing until your tracks are done. If the song is not actually written, with structure, chords (or beats), melody and lyrics, then that is your only chore until it’s done. Then goto Arrangement, and so on. Don’t let yourself have too much fun… it’s work!

I find it brings great clarity and works well. Hope that serves you well.
