Programming is weakening my problem-solving skills

Having knowledge outside of your head is what makes humans different than every other animal. I don't think there is anything wrong with looking something up. If I baked chocolate chip cookies 1000 times, but still checked the recipe each time, would all of the skills developed the 1000 times be out the window? Are you trying to memorize the recipe or the skills needed to complete the job?

Best of luck to you!

I like to start with the documentation for whatever I'm working on for answers, then if that doesn't work out do a code dive into the source if it is open source. I don't like leaning on Google-fu for answers because sooner than later you'll have a sufficiently unique problem that isn't already solved. You've got to know how to make some headway on your own.
