Yes, celebrate the successes:  The operation went well.  The talk was well received.  The family visit passed without
incident.  You arrived safely at your
destination.  The prayers worked
well.  Now you can relax.  Yes, relax, but do not stop praying.  We say this not to indicate that once again
you need worry.  We say it as a reminder
that the prayers kept you in a state of communion with Higher Consciousness.  Why should you go to this state only when you
need a favor?

In a world of duality
such as you inhabit whilst in human form, there will always be ups and
downs.  That is the nature of your
reality.  Do not pray only for the good
times and only in the bad times.  Pray ceaselessly
prayers of gratitude for the very communion you enjoy whilst in prayer.  It is this communion which sustains you.  Sustain the connection, and there you will
find the strength, courage, and peace of mind to travel well from moment to
moment.
