As mentioned already, everything is possible and sky is the limit. But...
... every person who plays soccer competitively asks himself, can I be like Messi, like Ronaldo?
... every person who plays basketball competitively asks himself, can I be like Lebron, like Jordan?
... every person who plays hockey competitively asks himself, can I be like Gretzky, like Howe?
And it doesn't go like that for for sports only (I'm kinda throwing Poker in e-sports category here, even though it isn't), but in all the areas where money and fame is involved. Everyone business owner or investor would like to achieve Musk or Bezos levels. Every scientist wants to discover or invent something groundbreaking. Every gardener wants his flowers to be most beautiful. Heck every Pokemon trainer wants to catch em all! Did anyone tried
Pokemon Black Cheats here?
The thing is that's it's perfectly fine to have a dream and many goals in your life and to try your best to reach them, but at same time for the sake of ones health and sanity it's good to also know the reality. And reality is that only an extreme few make it to the top of the world.
Sometimes you can do your best you can and you sadly won't make it.
That's why I prefer to have many smaller easier achievable goals. When I reach them it makes me happy and that's all that matters.
