you suffer more in your imagination than in reality. you replay conversations that never happened, worry about things that haven't happened yet, and create entire scenarios in your head that may never exist. you end up experiencing the same pain twice once in your mind, and again if it actually happens. stop making yourself live through problems before they're real. deal with life when it arrives.
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.
