This can also back fire.

I remember the days when people said programmers who don't use the internet/Google while coding actually learn more than those who do. While that was true initially- Eventually internet was just the norm and all pervasive. People who didn't use just got more unproductive, Same with companies.

Sure grind on whatever you are learning, but don't equate suffering with making progress. After a while do use the tools, you won't be building anything worth while without them.
