Of course we all get fun from pushing ourselves. Enjoying the journey. It's like buying scratcher lotteries. It's hella fun.My philosophy is to enjoy the journey of life irrespective of whatever destination it takes me to. So, I might never get to 5.0, but it is fun to keep pushing myself physically and from a technique standpoint to try and get there especially as I have the spare time and resources to get regular coaching now.
But if you ask about actually making money, or actually achieving "read ball better, select shots better" -- which is entirely different story --, the answer is stop dreaming.
