How can I focus only on programming to become an exceptional programmer
I’m not sure I understand. What do you think is preventing you for focussing on this (or any other) goal?
Is it that you’re too busy and you are having trouble having time?
Are you having trouble focussing in general?
For the latter, I might suggest setting some goals and maybe reading a book like Deep Work.
Perhaps if you shared more details we could offer better advice.
Why would you want to do this?
