Goodbyes are difficult, and looking back is tempting. What ifs are plenty and answers are few. I try, sometimes it is very hard, to walk today's walk without worrying too much about tomorrow and not thinking of the what ifs of the past. You need some basic securities to do so, though. I am weak, because I am not able to trust God that way, but need the work contract and the vision that things are doable before I stop worrying. I wish I could trust God more wholeheartedly, though.
