Keep sharpening your knives. Your brains are your knives.
• Planning meticulously,
• Assessing risks,
• Forward thinking with statistics and effects, Permutations and combinations for every activities and outcome,
• Expecting negatives but preparing for positive results,
• Revisiting the experience and learnings from every moment of life,
• Seeing beyond the horizon.
These are key attributes for self improvement.
Else you will land up just being an ignorant person with attitude. Such a combination is harmful.
