Obviously it's a different crowd at /r/powerlifting (and here, but I saw this video on the powerlifting sub first) than it is at /r/fitness, and I may be oversimplifying Stan's point here, but so many times I scroll through threads on /r/fitness where the answer to the OP's question is "you should try trying".

Try harder in the gym, try to eat better, try to sleep more, try to be more diligent with prehab/rehab. Push yourself; set goals and try to achieve them. There's so much paralysis by analysis and people looking for quick fixes, when really it just comes down to honest effort and accumulated progress over time.

A saw a similar post a while back that had some things I really agreed with:

Though the term "progressive exercise" has been used as a catchall to describe weight training activities, most trainees rarely make any attempt to actually have progressive and productive workouts. The "theory" is so logical as to be almost ridiculous, yet it is so often, if not always overlooked. If one were to add 5 lbs to the barbell every two or three workouts, or add another repetition, performed in proper style, with the same weight one used in the preceding workout, growth would occur ... as the system would be constantly exposed to an ever-increasing load. This is progression.

If the precepts put forth here seem simple, it is only because they are. Complexly so. Unfortunately, most trainees do not want to hear the simple truth. They feel safer looking endlessly for secrets, miracle potions - almost anything other than admitting that they are not willing to work *hard* enough for the results they desire (a rather common condition actually, but one most often denied).

Emphasis mine.
