Perhaps demanding certainty itself is a paradox. If seeking certainty is my goal, then no matter how much I study or train in this lifetime, I will never achieve it. Instead, I should plan every move based on the worst possible outcome, control risks as much as possible, accept the probability of failure, and seek a balance between failure and success, so that I can survive in this market for as long as possible. That might still be achievable. On March 15, 2026, I tossed and turned, unable to sleep, with suppressed emotions surging inside. Now, I can only rely on one thought: as long as life doesn't crush me, there's still a possibility for me to continue fighting against it.
