So this is called Algernon's law. That evolution has probably picked all the low hanging fruit, and it would be hard to find simple things that work. The counter example might be that we evolved to conserve energy. Now that we have basically limitless calories, some parameters set by evolution may not be optimal. There are also things like stimulants that seem to make people better able to focus on the task they want. Evolutionary this is probably suboptimal. Doing boring work without reward is probably a waste of energy other resources, and you should go find a task that is rewarding. IIRC hunter gatherers were found have higher rates of ADHD genes. Now being able to focus on boring tasks is a requirement for success, and ADHD is a huge curse.
