You can’t control people, whoever he/she is.
The only thing that makes you and your partner walk in synergy is the same vision. No matter how big the differences are between you two, no matter how huge your ego are. And, actually, there is something can strengthen your steps, it is love.
Without it, there is no tolerance, no flexibility, no hold backs, no motivation. And without it, there’s no fun on the way to your destination.
