Keep your problems smaller than your life. A flat tire is a flat tire. A bad meeting is a bad meeting. A canceled flight is just an extra two hours. These things become catastrophes when you let them. But they stay manageable when you remember the depth of your real life- the people you love, the work you care about, the beautiful years still ahead. Zoom out. Fit your reaction to the size of the problem.
A healthy relationship will test you more than a toxic one. Because it won't let you run. It holds up a mirror and says: Show up. Communicate. Grow. Swallow the pride. It's a repeated choice to stay and work at it together. Even when it's hard and ugly. That's why real love scares people so much in this generation.
