Hey there, pages 72 and 73 have guidance on Realization. I would say "When I push myself to the limits" is probably too broad, at least for my table, or at least without going in knowing that we'd really limit to "push myself to the limits" really far. A good rule of thumb for Realization is: Can it be falsified? I.e., could there be a situation where the user freely and unworriedly says "Yeah I can't use my sentence in this circumstance." If the answer is no, then it probably isn't Realized. So, if your table is really willing to judge whether you are "pushing yourself to your limits," then yeah, it probably works. But if you're just using it to characterize what the use of the sentence looks like, then no, probably not great.
