I was 45 when the company that I worked for as Chief Engineer was taken over by assett strippers. They wanted to flatten (and dispense with) my R&D dept to make a road into the rear car park to build property. I said 'its over my dead body', and it was! I remember the big boss telling me that I would one day thank him for chucking me out. Well I don't, but it started me on a path to being my own boss. I would never have gone this way on my own, and I am sad to say that that because new product development was halted that particular engineering business, which employed over 300 people and had been in business since the 1920's went down the pan.
After 16 years during which I looked forward to going to work every day, and earnt lots more money, I am glad I went down the route of starting a business. It was hard at first, but it has been very rewarding in many ways.
Be proud that you are an engineer, you have completed a really tough, academically challenging training. Its a waste for a real engineer to go down the tradesman route. Better to use your skill and knowledge to do your own thing, and build some sort of business around that, rather than simply fritter all that hard learned knowledge away on being a tradesman. Self employment, and building a business may not be right for everyone, some engineers are just 'meetings engineers', they have no skill except perhaps project management and organising ability. But even for them, there are possibilities.
Engineering teaches you to build things, build them right and and build them safe. Unlike Accountants, you can see into the future, and what could be, rather than just fill a sheet with figures telling what happened. You should be able to plan, project, and test the viability of a product, a service, or a project because that was how you were trained. Its a waste to squander all that skill and knowledge by simply become a tradesman. Unlike me, if you are dissatisfied with working for a platry sum for other people, give yourself the luxury of planning out your path to a more rewarding career, and make that jump.
