After a failed DIY attempt, hire a professional to the rescue,
then proclaim "I almost could have done it myself." A
margin distinguishes between a professional and an
amateur. The devil is in the details. Sometimes being 90% there is as good as
"...we almost made it to the moon (within
250 miles), the calculation was only 0.1% off. We've expended our propulsion
fuel and are in limbo." Well, congrats on a 99.9% success!
Another celebration is in order in a 1000 years as you spiral thru your
orbit and destine to become the "smash hit of the year" at the Sun.
