We know a little bit, but most of it is just theories and speculations.
Don't forget that we are experiencing a magical wonder that none of us can really explain.
After my education as an engineer I started the IT company WIS back in 1990. Yes, it was before Windows, the internet and mobile phone. We are now 10 people who develop software for businesses across the country.
I've had the pleasure to contributing in start up and running several organizations, and has learned a lot from that.
I have played clarinet and flute in bands and been singing i choires. I've been conducting many different choires and bands. And I play the piano in events and sing when I have the opportunity.
Sometimes I participate in events to share experiences and try to give some inspiration when needed.
