Becoming uninspired is a side effect of having one’s life drained out of them.
Do not hang around or work for vampires. They are people who think exchanging money of life is equitable, and the one providing life doesn’t know any better.
One should always find value in their own life so that when they do exchange it for something like money, they get full value. Also they should pick clients for their time that will help nurture their own life, so the return on investment is of the highest value.
As for the vampires, the are generally not doing this out of maliciousness, but after pursuing the wrong fruit. Invest into one’s labor and they will provide better fruit for one’s return. Also not all laborers need the same type of investment, sometimes it is as simple as coaching.
