Many of our fears and anxieties exist in the imagination. We ruminate over future events that may never come to be. I might be late to work. Inflation might increase my mortgage rate. That small bump might be cancer. We don't know that these events will become reality, but in obsessing over them we limit the joy we find in the present moment.
Should we then ignore the future and focus only on the here and now? This is a tempting solution, but it may leave us unprepared for life's challenges. Perhaps a better solution is to underscore the word "might". There are many possible futures. Some become reality, but most do not. We should prepare for possible futures objectively. If we rehearse these events by somehow removing ourselves, then we can prepare without torturing ourselves with anxiety. Play out future scenarios in the mind as if they are happening to someone else. Doing this requires no fear or suffering.
We know bad things happen. So, we should not be surprised when things go wrong. Preparation can help us deal with bad luck when it occurs. The trick is to avoid fearing things that may never happen.
