One person brings the beat, another brings the words. Together they make what neither could alone.

Collaboration is not about dividing labor so much as about producing something neither person had access to alone. Your limits and theirs do not overlap, and the work that appears in the gap between them belongs to neither of you individually. That is the whole reason to do it.

Find one person whose strengths cover your weaknesses and start something small with them. Agree early on who decides what, since most collaborations fail on that rather than on talent. Then let them change your part, which is the hard bit and also the point.
