Look for these 2 attributes in people when deciding to work with them or invest in them:

“Hard to kill” – Do they keep getting up even after getting knocked down multiple times? Do they persist and keep pushing forward? If so, these are the individuals you want to hire and entrust. Seek out their stories and anecdotes; their actions during challenging times, when the only way out was to persevere, will reveal their nature.

“Are they before the fall or after the fall?” – Has life humbled them, leading them to recognize that success, happiness, and progress result from a blend of hard work and luck? Despite adhering to rules and putting in the effort, life can deal with hardships—misfortune, illness, betrayal, accidents—that can be crushing in business, personal matters, and spiritually. But they get up and keep going. Hire those people because they have been humbled but kept going. You can normally see it in their eyes when you spend time with them.
