Part 1: Adopt the Right Mindsets

Focus on High-Leverage Activities

How should we decide what actually to work on in order to more effectively achieve our goals? Assess the activities' leverage:

Leverage =  (Impact Produce) / (Time Invested)

Another way of thinking about leverage is the commonly-mentioned Pare- to principle, or 80–20 rule—the notion that for many activities, 80% of the im- pact comes from 20% of the work.

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.
