um my limit is the point at which my mind can't give suitable reasoning so limit for me is "what something is " Richard Feynman once said " the glory of mathematics is that we don't ve to say what we are talking about , the glory is that laws argument and logic are independent of what it is " so we can describe things in great way but we don't know what it is ... here limit is so obvious

the words called wrong... this limits me...

The sky is my limit.
