Isn't fame a weird thing? Nobody cares about you when you're an unknown or before fame. Reminds me of Daniel Ricciardo before he started winning. Nobody batted an eye in the paddock.
Once he started winning, it was like that Ronaldo video as well as endless autographs.
Then your career perhaps slumps, people jump on the has been bandwagon. Or, they die. Everyone says he\she was the best at whatever they were, next move on. Reminds me of Bowie, everyone was saying he was the best, ever! Then Prince dies, he was the best, ever!
Or Lewis Hamilton for example. Every F1 race he says this is the best circuit on the calendar. Next!
Everything is just a flash in the pan and most of the time most people have forgotten as the weeks/months and years pass. Oh I remember that now!
