Keep it Complex, Simple

I've been hung up on the plot for my contemporary wip. Thinking I was going off on a tangent and making it all too complex, I've spent the last few days mulling over ways to simplify motivations and the backstory between heroine and hero.
But today I had a breakthrough- by introducing 2 new levels of complexity, everything fell into place and sorted itself else. Just a reminder that living life is complex, tangents come at you out of the blue from all angles all the time... it's a lot harder trying to simplify our character's lives than making them real 3D people with all the fears, faults and chaos of life
