Bands are delicate ecosystems, even when there are only two members. The weirdness that exists between members can be the trigger for really special music, the little pocket out of which a very specific kind of creativity grows. That weirdness can also be the reason a band doesn’t last very long, or makes bad music, or lasts too long when nothing satisfying to any of the members is happening... or something even worse.
For this reason, it’s helpful to be selective when forming your band and to be able to spot red flags in potential bandmates. It may sound like a sterile, uncreative approach, but at the end of the day, your band is like a business. You may appreciate someone’s creative genius, but if his/her personality or habits don’t align with yours, it’s unlikely it’ll be a sustainable partnership.
