Well, I have a task that I overestimated and won't be able to complete with my 180. It isn't so much that the 180 failed me, it is either I ran out of time, or I didn't manage it properly, or both. I was digging out of a hill side to fill in my pool. I've finished about 1/3 of the pool, but now we are moving earlier than expected and have to sell the property fast. I'm buying fill dirt to finish the pool and scrambling to make the hill side that I dug out pretty with a terracing wall.
I thought that it would go much faster than it did, and underestimated how much dirt it would actually take.
