>What can be unburdened by what has been
Well, yea. If you take a fragment of a sentence out, it is going to be confusing.
The full quote is on the lines of "My mother raised me to see what could be, unburdened by what has been" i.e. to look at accomplishing at the highest possibilities without the baggage of traditional limitations
Reading it now and in context, its a normal impactful thought. But the right took a cut off the middle... like if I quoted you and said "a native English speaker and half the time" a missing phrase will obviously make it confusing
