How long does it take to reach some goals? Well, some are achieved relatively quickly, but others, well, they can take many years.
Take a look at the journey of Jason Day from starting out to number one in the world.
How many tournaments has he played in?
How many practice shots has he hit?
How many poor rounds has he had?
How many times has he wanted to give up?
How many miles has he traveled?
How many dollars has he invested?
How many years did it take him?
The road is longer for some, shorter for others. But whichever way you choose to look at it, it is not for the unrealistic.
However, if you are extremely determined, well funded, have a great team of experts around you, and you have the capacity to continually seek improvement despite constant set-backs--and you can really play, then there's nothing really stopping you from chasing your dream.
Just remember that it is a very long and winding path, and most travelers will give up along the way.
That's why there's so few at the top...
But don't let that stop you.
