It’s an easy thing to make yourself feel insufficient: simply pick a task that is beyond your reach. It can be a nearly impossible physical task, like running a long distance. Or a mental task, like memorizing a long work of fiction. Or it can be a social task, like having plenty of fans and friends. Regardless, it can be something you can be guaranteed to fall short of achieving in the attempt.
(You might exclaim: who’d do something like that to themselves? But people do something similar to that all the time.)
The hard thing is to make yourself feel sufficient. To look past your failings and limits and judge yourself worthy. It requires knowing yourself. Knowing what is required of you. Knowing that even if you can’t do everything or even many things, you still can do some things, and that those things are enough. Those things are sufficient. Just like you are sufficient.
