A lot of what we file under worrying is habitual and automatic, based on the underlying beliefs we hold. Change those beliefs and a whole slew of things we worry about evaporate.

Also, the most important element of worrying is this: it is a use of the imagination and we worry to the extent that we feel the importance of things outside of us and our own lack of control about them. The more we build a self-image as creators, instead of as reactionaries (or even victims), the more worrying can become positive imagining.

The simple fact is that we will never be able to cease thinking about the future. What we can absolutely choose is how we think about it.
