To be a better programmer, write little proofs in your head

- Develop the habit of mentally proving your code's correctness as you write it to improve accuracy and speed.
- Look for monotonicity in code to simplify reasoning about processes that only move in one direction.
- Use pre- and post-conditions to define and verify the behavior of functions, aiding in unit test creation.
- Maintain invariants in your code to ensure certain conditions always hold true, regardless of execution path.
- Isolate changes to minimize their impact, using structural 'firewalls' to prevent unintended side effects.
- Apply inductive reasoning to prove the correctness of recursive functions and data structures.
- Design code with 'proof-affinity' in mind, making it easier to reason about and verify correctness.
- Practice writing mathematical proofs to sharpen logical thinking skills applicable to programming.
- Use resources like algorithms classes and coding platforms to practice and improve proof-based reasoning.
