According to some of Socrates famous quotes he said “There is only one good, knowledge, and one evil, ignorance.” And he advised others to know one self is the beginning of wisdom.” And the best source of wisdom can be gathered from the message of the Quran as stated in Surah 36:2 “By the Quran full of Wisdom” and here is where Allah provides you of your fundamental characteristics:-

Man is not independent he rely upon others to help in his work, his family in the household to love and care, his friends in his leisure time for social and sports and most important the time he has to reserve for his Creator. For there is the ultimate spiritual provenance where the time he can learnt and understand who he really is and react positively with the correct information he has to be a better person and to lead a beautiful live in this world and the next. Here are some fundamentals one should understand about one self.

Man is dependent.
>>>>>Surah 4:28 – Allah doth wish to lighten your (difficulties): For man was created Weak.

Have the attitude to be generous when making a settlement we react negatively.
>>>>>Surah 4:128 – If a wife fears cruelty or desertion on her husband’s part, there is no blame on them if they arrange an amicable settlement between themselves; and such settlement is best; even though men’s souls are swayed by greed. But if ye do good and practice self-restraint, Allah is well-acquainted with all that ye do.

Be in control of one own soul it can be more disastrous even without the Devil. See the two characters of the son of Adam and Samiri of the people of Moses respectively is representative of a lost soul.
>>>>>Surah 5:30 – The (selfish) soul of the other led him to the murder of his brother: he murdered him, and became (himself) one of the lost ones………. And the other was the culprit of sculpturing the golden calf who confessed in >>>>>Surah 20:95-96 (Moses) said: “What then is thy case, O Samiri?” He replied: “I saw what they saw not: so I took a handful (of dust) from the footprint of the Messenger, and threw it (into the calf): thus did my soul suggest to me.”………And stated in >>>>>Surah 10:44 – Verily Allah will not deal unjustly with man in aught: It is man that wrongs his own soul.

Man will never stop disputing.
>>>>>Surah 11:118 – If thy Lord had so willed, He could have made mankind one people: but they will not cease to dispute.

Be thankful and never regret with what we have
>>>>>Surah 14:34 – And He give you of all that ye ask for. But if ye count the favors of Allah, never will ye be able to number them. Verily, man is given up to injustice and ingratitude.

Not only learn to spend for the less fortunate but also the wisdom to strike a true balance.
>>>>>Surah 17:100 – Say: “If ye had control of the Treasures of the Mercy of my Lord, behold, ye would keep them back, for fear of spending them: for man is (every) niggardly!” >>>>>Surah 17::29 – Make not thy hand tied (like a niggard’s) to thy neck, nor stretch it forth to its utmost reach, so that thou become blameworthy and destitute.

It pays to be patience.
>>>>>Surah 21:37 – Man is a creature of haste: soon (enough) will I show you My Signs; then ye will not ask Me to hasten them! And further it is stated in>>>>>Surah 70:19-21 – Surely man is created of a hasty temperament. Being greatly grieved when evil afflicts him. And niggardly when good befalls him.

Remember the day will come to be accountable for our action.
>>>>>Surah 21:34 – We granted not to any man before thee permanent life (here): if thou should die, would they live permanently? 56:60 – We have decreed death to be your common lot, and We are not to be frustrated.

Do not waver life is a trial.
Surah 25:20 – And the messengers whom We sent before thee were all (men) who ate food and walked through the streets: We have made some of you as a trial for others: will ye have patience? For Allah is One Who sees (all things).

Life is a struggle it is best being steady.
Surah 84:6 – O man! Verily thou art ever toiling on towards thy Lord- painfully toiling, but thou shalt meet Him.>>>>>Surah 90:4 – Verily We have created man into toil and struggle.

Be a believer and obey the Lord by doing righteousness.
Surah 100:6-11 – Truly man is, to his Lord, ungrateful; and to that (fact) he bears witness (by his deeds); and violent is he in his love of wealth. Does he not know when that which is in the graves is scattered, and that which is (locked up) in (human) breasts is made manifest- That their Lord had been well-acquainted with them, (even to) that Day? And in >>>>>Surah 95:5-6 – Then do We return him (to be) the lowest of the low, except such as believe and do righteous deeds: For they shall have a reward unfailing.
