I watched a good TED talk on happiness. The speaker said there are three components of happiness…miss any one, it spells trouble. They are enjoyment, satisfaction and purpose. This explains to me why so many of us have what ought to be ideal lives, but don’t really turn out like that. I used to play 5 or 6 rounds of golf a week. Fun, enjoyable, but… not good. No purpose. I volunteered at the local railroad museum and ran the big lathe and mill. Some of the people were great, but some were just outrageous…not enjoyable. But I have 5 patents in the field of nuclear fusion energy, and have a small team of remarkable people…the “work” is terrifically fun, a combination of lots of the projects talked about here, infinite shop machine work, electronics design, software development, vacuum systems, machining titanium and erbium. etc.
And as you can imagine, any success would have immense implications. So now I have the three factors under some control, and I can say this really works. We would all have different solutions, but those three factors have to be satisfied.
Good luck!
