Unfortunately those above have said it better than I can.

The only time I was indispensable was when I managed an automotive machine shop supervising heads,hot tanks,align boring,semi-sizing and babbit pouring.

THAT didn't last forever,but I gained a great deal of experience and a lasting distaste of working for others,thank the Gods I can control my own destiny.

The only way to profitably utilize your skill and knowledge is to get financial backing and supervise others to do the actual work,I and a friend have set up a shop for restoration with upholsterers,a machinist and a painter,I stop by daily to check on what's happening and occasionally do the mechanical assembly and measurements myself.

Here's the rub...they're all Cuban,Mexican and Nicaraguan,the polisher and final detail guy is 100% American which explains why he always argues about why he is late for work..............
