It is so difficult not to anticipate difficulties or let excitement drift over into anxiety that everything goes smoothly, which of course it never does. This living in the moment thing, whether the moment is "good" or "bad" (and most things are some of both) has been a lifelong challenge for me.
But to the extent I have learned to be grateful at all times, in all places and circumstances I have known more peace and been better equipped to be my best self. I have read quite a lot about grief over the years, trying to understand loss and moving forward and healing. I remember reading that even good things have an element of grief in them: joyful new babies come with little sleep, new homes come with lost neighbors, and new jobs come with loss of close contact with co-workers and mentors. I have learned that even the challenging things come with blessings: sharing the care of an ill beloved one with others who love and value them, experiencing loss of job or relationship and being reassured that we have people who are in our corner, cheering us on.
So, my friend, whatever you are waiting for today, I commend to you this verse
Philippians 4:6-7 Don’t worry about anything, but pray and ask God for everything you need, always giving thankfor what you have. And because you belong to Christ Jesus, God’s peace will stand guard over all your thoughts and feelings. His peace can do this far better than our human minds.
