I have various tools from extended family. At one point I had decided to mark them with initials of the previous owner. I have come to the conclusion that nobody will care. Since the next generation will not have known the person it came from, it will have no meaning for them. I have come to the conclusion that everything I have built will mean nothing in less than 200 years.
We did inventory Thursday and Friday last week and due to the way it works, after I am done with my department I have nothing to do. I learned this last year and took my Kindle this year. I was reading "The Einstein Theory of Relativity" by H.A. Lorentz when the CFO walked by and asked what I was reading. Einstein happens to be one of his heroes and we have had several discussions now on him and his work, including the cosmological constant. I find it interesting that people like Leonardo DaVinci and such are remembered for thousands of years, and I will be forgotten 50 years after I die.
I have come to several conclusions in my life thus far. One, I am not going to mark the tools. Two, the best I can do is to do the best I can where I am at. Three, people are more important than things.
