It's very difficult to land any roles as an actor, let alone large roles, and so someone who has been trying for two years without any success is likely to feel like they've been working very hard with no results
Context: "I've been grinding for two years as an aspiring actor and I have yet to land any large roles."
Hypothesis: I've been working my ass off for two years as an aspiring actor and I still don't have any large roles
Based on the context, is the hypothesis true, false, or unknown?
