At this point it was found that even the love of friendship failed to provide the happiness being sought, since even in Platonic (non-sexual) friendship jealousy and disappointment can arise. A stronger and more extreme doctrine was indicated. Epictetus and Marcus Aurelius (a slave and an Emperor) revived the ancient Greek philosophy of Stoicism. Stoicism was a philosophy of spiritual resignation. It rested on a distinction between the things within our control and those beyond our control. All things beyond our control must be accepted. Not to do so is to multiply our sorrows. While we cannot control things that happen to us, our reactions are within our control. Friends may desert me, but that is predictable and should not surprise or grieve us. Our hearts, expressions of the spiritual fire of god, should burn like candles untouched by the winds of fate or fortune. If we consistently pursue this path of wisom, we will attain the state of APATHEIA, freedom from all pathos or suffering. Thus, the Stoics agreed with Lucretius that happiness is freedom from suffering, but offered a more thorough-going prescription for achieving that condition. While Stoicism was adopted by some Roman nobles as consistent with traditional ideals, it remained a philosophy of defeat rather than victory. A Roman general, as a Stoic, had available to him the option of suicide if he was ignominiously defeated, an act he could carry out consistently as a good Stoic.

Nobody can work alone. It is human nature that we seek help in things that we do because we do not have the knowledge about everything and not everything can be under our control. And this group of people working together, we call them, a team.
A team is successful only when one understands the importance and the intricate workings of a team. One of such is having a team leader. A leader is there to arrange for a meeting, to organize his team's activities and to guide his members when they are confused. He should be someone the team is able to trust and respect. A team leader must be decisive and willing to speak out because he will be the representative or the medium between his team and all others.
It is also important for a team to be able to share their information efficiently. It is a part of working together and a good test on communication skills. No members should be selfish and keep to themselves because a missing information from an individual might just cause the fall of a team. This is why it is important to have meetings and contact numbers from all members so messages shared efficiently.
Another important element in a team is responsibility. It is crucial to know one's responsibility in a team. Usually, the decision on the responsibilities would fall on the leader based on the members' abilities and interest. Otherwise, sometimes, voting is a good option for decision making if there is too many people opting for a single job. Only when the responsibilities are well distributed, can a team work together and complete their task.
In a nutshell, we should never take our team for granted. We should always fulfil our roles to the best that we can, accept all our differences and tolerate each other's habits. Only when we have managed to do these, we can call ourselves, a team.

Exercise daily. Regular aerobic exercise improves circulation and efficiency throughout the body, including in the brain, and can help ward off the memory loss that comes with aging. Exercise also makes you more alert and relaxed, and can thereby improve your memory uptake, allowing you to take better mental “pictures."
Reduce stress. Chronic stress, although it does not physically damage the brain, can make remembering much more difficult. After prolonged stress the brain will be damaged. Stressful situations are recognized by the hypothalamus, which in turn signals the pituitary gland. The pituitary gland secreted adrenocorticotropic hormone (ACTH)which influences the adrenal glands to secrete adrenaline and later cortisol(corticosteroids). The corticosteroids can weaken the blood-brain barrier and damage the hippocampus(the memory center). Ironically, the hippocampus controls the secretion of the hormone released by the hypothalamus through a process of negative feedback. After chronic stress it will be damaged and it will not be as efficient in regulating the degenerative corticosteroids and memory will be harmed. Neurogenesis (formation of new neurons) indeed exists in the hippocampus but stress inhibits it. To recapitulate and synthesis, chronic stress will affect your health and your memory, it will damage the brain so the best option is to learn to control stress. Stress will never be eliminated, but it definitely can be controlled.
Rehearse information frequently and “over-learn”. Review what you’ve learned the same day you learn it, and at intervals thereafter. What researchers call “spaced rehearsal” is more effective than “cramming.” If you’re able to “over-learn” information so that recalling it becomes second nature
