Duplication through quote misattribution: Lincoln or Drucker

[pscheid92]

Searching the quotes.json file, I detected a duplicate quote attributed to two different authors.
As discussed in issue #41, we should check the attribution and remove the duplicated entry.

{
    "author": "Abraham Lincoln",
    "source": "https://www.goodreads.com/quotes/328848",
    "tags": "future, prediction, create, creation, life",
    "text": "The best way to predict your future is to create it."
}

{
    "author": "Peter Drucker",
    "text": "The best way to predict your future is to create it."
}

@pscheid92 thanks for opening this issue as part of the de duplication and cleanup effort. 🎉

I know Goodreads isn’t a particularly good source of credibility in terms of verifying attribution, but the link in the Abraham Lincoln one https://www.goodreads.com/quotes/328848-the-best-way-to-predict-your-future-is-to-create seems plausible enough …
and yet Drucker was a forward thinking guy so he could easily have said it too:

I’m a bit torn on this one.
Drucker wrote a book called “Managing for the future” (great read from a historical perspective BTW). So I’m inclined to believe the quote is attributable to him even if he was merely repeating it and not the original author. 🤔

I found an article on checkyourfact.com ruling out Lincoln.

The website Quote Investigator has tracked down these and other variations of the phrase, none of which credibly belong to the nation’s 16th president.

The statement appears nowhere in his collected writings, according to Daniel Worthington, director of the Papers of Abraham Lincoln. “I am not familiar with the quote, and I could not find it in any of our documents, so I have my doubts Lincoln said it,” he told The Daily Caller in an email.

According to this article Peter Drucker used a similar quote, but not the same:

This expression has multiple variations. In a 2009 book, the management consultant Peter Drucker was quoted as saying, “You cannot predict the future, but you can create it.”

It seems checkyourfact.com goes with the conclusion of Quote Investigator and attributes it to Dennis Gabor:

The saying may have originated with Dennis Gabor, the physicist who won the 1971 Nobel Prize for inventing holography. “The future cannot be predicted, but futures can be invented,” he wrote in a 1963 book. “It was man’s ability to invent which has made human society what it is.”

Shall we go with Dennis Gabor, then? 😅

Yeah, Dennis Gabor https://en.wikipedia.org/wiki/Dennis_Gabor for sure. 👍
We can also revise the one for Peter Drucker (even if is very similar). 📝
Remove the Lincoln one as it's virtually impossible to verify. ✂️
