As someone who has had a few articles published, may I say that I'm in it for two reasons:
1. For the joy and delight of seeing my name in print as the author, especially as I have no training in engineering, nor of writing technical articles; and,
2. To support a choral society that I was a member of for 21 years until hearing problems put paid to my singing. In this instance, the payments go directly to the society, and I make nothing from it.
I suppose it could be argued that I am doing it for the money, albeit to support the choral society. On a personal basis, I don't need the money, hence the choral society benefitting.
