Yes for sure! There's no hard and fast rule, it's all guidance. And everyone has their own way of approaching a problem. I'd still suggest using a timer to set how much time you hack on a problem. In a job you might not want to spend too much time on a task. And even though you might happily hack away, it may be a detriment to your work.
A timer is also a nice break, and a point to pause and reflect on how far you've gotten!
Thanks for the response!
