Some principles are universal (e.g. you get what you give)… but not all. Some principles are situational and have mirror images with which they may compete in any given situation.
| Yin | Yang |
|---|---|
| Go the extra mile | Do the simplest thing |
| Planning is procrastinating, just do it | If you fail to plan, you’re planning to fail |
| Don’t cut corners | Eliminate what’s unncessary |
| Standardization and structure enables long-term progress | Long-standing problems are solve by thinking outside the box |
| Live in the moment | Prefer a Long-Term Philosophy |
| The bird in the hand is worth two in the bush | Nothing ventured, nothing gained |
| Use what you have | To a hammer every problem looks like a nail |
It seems as though Mastery is Knowing What You Actually Need would also apply to the given principles that best apply for your situation.
