Personal fulfillment in life bears a deep meaning when we remember the obstacles we have to overcome through our determination. Never give up. A lion may change course or target, but never gives up. No one will ever know you had a goal to achieve if you give up. Jungle animals survive together.
Lions hunt together, sometimes in packs of four or five to bring down a water buffalo.
In our jungle we have to have associates we can work with or depend on. Know when you are safe. Either from your predator if you are a gazelle, or with your meal if you are a lion. This is directly related to having a specific goal. Same with a lion - when it has its kill, that's success.
