Citing Sources, and why this is essential
Theo, when editing Wikipedia articles, it is vital to distinguish two things that may look similar:

1) things you believe or "know" to be true, and

2) things you can prove to be correct, by citing a Reliable Source to enable other editors to verify that what you say is indeed correct. Without this, anybody can write anything and claim it's their personal experience, they met the famous footballer/philosopher/celebrity/... who said ... or perhaps didn't ... and we don't have a dependable encyclopedia any more.

Wikipedia always uses (2), and I hope it will immediately be clear why that is.

With my best wishes, Chiswick Chap (talk) 15:55, 1 December 2020 (UTC)
