A certain amount of frustration is expected if you set the goals high. But an excess of frustration becomes counter-productive and should signal it's time to change strategy. It doesn't mean "give up forever" but rather "try getting to midpoint first, then reevaluate".

It's surprising how effective being lazy can sometimes be. Some tasks that could be brute-forced seem to magically melt away if you adopt round about ways and let time pass. It's a latency/throughput tradeoff.
