No one knows what the future holds. Just ask Wall Street. It can be easy to let analysis paralysis set in and keep you from doing much of anything, because the fear of "what if...?" makes it sound dangerous and scary.
You know what, the future is scary at times, just like the past was scary at times. The future is rosy at times too, just like the past was rosy at times. You can't let it stop you from doing great work. I'm editing the video from Mt. Rainier, trying to condense it down to 10 minutes, and wow what a beautiful day that was! If we let fear seep in and overwhelm us, we will never be able to experience things like that.
