An excellent post good sir.

All true, it's my mental resistance that makes certain tasks hard to do.
Try to do paperwork, but first you strap yourself to a wild horse and scare it. It's a pretty silly thing to do but it's essentially the same thing.
Everyone can send a half assed job application. The basics of sending a job application is something every normal person can do, the only hindrance is mental resistance to the consequences of doing so.
There is however work that is hard or impossible for a different reason. But that's hard in a different meaning. That is work that requires a certain level of skill. Game development newbies can't produce AAA titles right away. No matter how much they try it still takes many years to reach the level of skill required to do something that great.
So hard work is either a matter of releasing the brakes and push the gas, or it's a matter of training. Depending on what the work is and your skill level.
