Mammals are characterized by their active lifestyle. They are walking, jumping, swinging in the trees. They find food very proactively. They search for the prey by breaking their camafloge code, secretly get near them , chase them and catch. They also employ superior strategies to catch the prey. Wild dogs work in a large group and catch the prey of any size by merely tiring them. Lionesses surround the large prey from all sides and chimpanzees insert wooden sticks in ant hills and catch the ants that hold on to the stick.
Despite this the best success rate killers like lions achieve is 33%. Mammals waste a lot of energy in searching for food, which if conserved would reduce their need for food. Proactive search for food or business has a built-in risk of wastage. One has to run equally hard for each kill, with20% conversion rate generally seen in business transactions 1 in 5 will succeed. All unsuccessful chases would leave you feeling exhausted, frustrated and filled with self doubt.
Consider a reptiles strategy on the other had. They are passive hunters. They position themselves where food would unsuspectingly come to them. They have patience to keep steady till the kill is in the striking distance. Once the kill is in range they move very rapidly, use secret weapons like camaflouge, poison or hypnotic sounds to catch the prey. Reptiles are cool, aka cold blooded. They have better work life balance as they take long vacations in their hibernation spots. Well all this gets them spectacular results too. Compared to mammals of same size, reptiles have longer life span.
If you are tired of being a mammal at work, if futile chases are demotivating you, if wasteful activities are sapping out precious time out of crunched schedule, its OK to be reptile. Its OK to wait for the opportunity or the customer to walk up to you. Its OK to take a long vacation and recharge your batteries. Its OK to be cool than just running around. There are chances you will not burn out and survive longer in your job!
