There comes an inevitable point working in #data where you can't figure it out. You waste hours. Maybe days. Maybe weeks. Trying to hack the problem.
And that feeling can leave you shaken and leery to go back to difficult problems. At least that's my experience. It's part of why I have such a hard time getting myself to learn something new.
It's not that I can't. It's not that I don't want to. It's knowing that doing something new leads to a high likelihood of experiencing that "ick" again.
