+# Individual Ability
+
+**Effort is the smallest part of improvement.**
+
+This note is about practical ability.
+For discussion of how others _perceive_ ability,
+see [[professionalism]].
+
+Individuals differ in **learning rate** and **capacity for familiarity**.
+Whether nature or nurture is to blame,
+there is little an adult can do to move those needles.
+Making the most of the resources you have
+requires developing effective coping mechanisms
+(like [[notetaking]]).
+
+To gain and maintain skill is time consuming.
+The barrier to greater professional skill
+for most people is **responsibility**.
+
+## Capacity for Familiarity
+
+There is a practical limit to the mind's "shelf space".
+It's not only a question of experience or exposure,
+familiarity requires maintenance.

+## `TALK`
+
+I want to use this note to talk about
+what makes an expert and
+what makes an "expert".
+
+* imposter syndrome
+* effectiveness vs productivity
+* traits valued by employers/clients
+* being a "salesman" of your abilities
+
+### Being a Salesman of Your Ability
+
+To "sell" something in the sales sense
+is to make it more appealing _without changing it_.
+A cynic might call this lying.
+A more fair take is that people generally present their ability as less than it is.
+
+I suspect that the most knowledgeable
+and technically effective practitioners of any field
+are not known to be such.
+
+To be a salesman of some ability
+is a deviation from specialization in that ability.
+Every bit of [[individual-ability#Capacity for Familiarity|capacity]]
+devoted to salesmanship
+is a bit less to the skill itself.
+
+> [!example]
+> Mike Holt has a better grasp on code than most,
+> but there are likely hundreds better than him
+> specifically in that aspect.
+>
+> It is his salesmanship, his visible confidence in his ability,
+> that makes up the difference.
+
+### Optics, or Playing the Game
+
+#### Example: Notetaking
+
+note-takers always look more valuable than they would otherwise.

+# Resolving Process Uncertainty
+
+## Process Uncertainty Resolution Steps
+
+1. **Check your [[#Writing Process Notes|notes]]**
+2. **[[#Asking Process Questions|Ask]] a ==peer== whose answers you trust**
+3. **Ask your immediate supervisor**
+
+Only escalate if you are still uncertain.
+
+## Writing Process Notes
+
+<!-- TODO: -->
+
+### `TALK`
+
+Taking notes has many benefits,
+many of which I would not list as such
+
+* **deferring responsibility:**
+
+* **optics:**
+  note-takers always look more valuable than they would otherwise.
+
+### Citation
+
+When you get an answer to a [[#Asking Process Questions|question]],
+or otherwise get some useful direction
+that you expect to use later,
+You should add it to your notes as soon as possible.
+
+With any direction you should include:
+
+* **who** said it,
+* **when** they said it, and
+* **what** it was in reference to.
+
+```md
+> [!quote]
+```
+
+## Asking Process Questions
+
+Ask your question as succinctly as possible **first**,
+provide background or complications **after**.
+
+Prepare for any obvious clarifying questions.
