Lots to do with future plans and changes. Change is always there and you have to adapt to it. I have most things set. Mission, job, marriage, school, not necessarily in that order. Having the fear that I could have the major things change rather than just the timing and order is one of the scariest things. Peace of mind has been a topic that has come up a lot lately. Just getting that comfy feeling without worries. For me I have prayer to help and a good video game usually helps.
