1. Imitate, then innovate - Knowing how to be great before becoming great while developing your own sound.
2. Write a weekly comprehensive self-evaluation - addressing your improvements/weaknesses, noting what works and what doesn't
3. Delete the worst tracks (or the most mediocre ones) you've made every month. Compete with your very best to remain consistent.
4. Have multiple backup devices and schedule a backup ever 1-2 weeks (project files, samples, documents, track log, songs, Project settings etc.)
