Seconded, there should be a rule that says you must have tried to make everything included in bootstrap at least once yourself before your allowed to use it. Otherwise how will you learn? That way when you do use it you'll have the knowledge to use it properly (and hopefully within moderation) well and you'll appreciate how much easier it makes life that much more!

The same can apply to all frameworks and libraries, both front and back end.

I'd go so far as to say that after a certain level of experience, everyone should implement a compiler/interpreter. Automation is awesome, but it's better not to treat them as "magic".
