Frustration is not the end of success, but a signal of wrong direction; failure is not a judgment of character, but feedback on the path. 1. Stop blind effort and review the underlying logic of failure. 2. Strip away emotional interference and turn frustration into data. 3. Lower initial expectations and focus on small improvements. 4. Find a rhythm to relax, as rigidity is the biggest enemy of efficiency. I used to learn swimming by just practicing hard, but the more effort I put in, the more I choked on water, falling into self-doubt of "I can't do it." Later, I stopped racing with others and instead observed the buoyancy of water, adjusting my breathing timing. Now I can cross easily and understand that so-called bottlenecks are often just overextending in the wrong direction. Are you desperately trying to tread water to avoid sinking, but forget to look up and see the direction on the other side? Effort does not necessarily lead to success; sometimes doubling down actually reinforces the mistake. When you sink in the pool, the most effective action is not struggling, but relaxing. In the adult world, admitting "this way is blocked" requires more courage and wisdom than "persist to the end."
