This answer is a bit more specific to what program I started with (FL Studio) — but organisation! Colour coding, naming, etc.
Another one I’m still learning and struggling with is not to sit on songs. I have 20+ 90% done ideas that I should finish and get out. Sometimes waiting for that ‘spark’ to come back is detrimental. Trust your talent and finish it.
