If you do one thing long enough, even if you’re mediocre, by virtue of being the last man standing, you’ll become a domain expert.

Let me give you the name "Bitcoin", you will be making good returns if you just keep buying the Bitcoin alone for how long you can. People who bought them in 2010-14 are probably enjoying their life in their billion dollar mansions.

Also it's not just about buying, it's also about holding long, people get the satisfaction after making 50% or even 200% returns but only very few are hungry to make it bigger than ever.
