long ago @wbialek pointed out to me the irony of his 2 most infamous quotes 
  - 1) "If your result needs a statistician then you should design a better experiment." and 
  - 2) "All science is either physics or stamp collecting."
is that, 
  - in the first case, his field of particle physics ended up 
  becoming far and away the most statistics-dependent of any subfield in physics, and 
  - in the second case, that his Nobel prize ended up being in chemistry not physics

  Allegedly a favorite saying of Napoleon’s. Later, Lenin.
  - t1: "You commit yourself; and then, you see."
  - t2: "First engage in a serious battle and then see what happens."
  - t3: "One jumps into the fray, then figures out what to do next,"

a good ask:

a good ask to a person (target) should

• include a warm intro to target from someone trusted by the target
• provide evidence of similarity or social connection to target
• show understanding of target's perspective
• explain how target was selected
• show evidence you understand the field you are asking about
