What is the advice for youth to avoid excess and negligence?

Question:
I am a young man who has taken the path of guidance, and praise be to Allah, but I turned to seeking religious knowledge. Then I suddenly left religious knowledge and turned to da'wah (calling to Islam). Then I left da'wah and a desire came to me to go to jihad. I want you to clarify for me the best way to be a balanced young man without excess or negligence, and may Allah reward you with good.

Answer:
In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, and may Allah send blessings and peace upon the Messenger of Allah, and upon his family and his Companions, and whoever follows their guidance.
As for what follows: Seeking knowledge is an individual obligation for all Muslim men and women; because there is no way to know the worship for which everyone was created except through knowledge. You heard a little while ago that we were created to worship Allah, as He, Glorified and Exalted is He, said: [Surat al-Dhariyat: 56]. And we do not know this worship except through knowledge of what Allah and His Messenger said. So seeking knowledge is necessary for males and females. A person must learn from knowledge what he cannot afford to be ignorant of: How does he worship his Lord? How does he pray? How does he fast? How does he pay zakah? How does he perform Hajj? He learns what he cannot afford to be ignorant of.
So if Allah grants him the knowledge that is obligatory upon him, and he becomes clear-sighted in his religion, and he loves to devote himself to seeking worldly matters: for trade, for craftsmanship, for agriculture, there is no harm, provided he does not turn away from knowledge. Rather, he remembers knowledge, attends the circles of knowledge, and interacts with the people of knowledge; so that he does not forget knowledge. And if he loves to devote himself to jihad, likewise, for jihad is a great matter, its benefit is great, and it is among the best of deeds. Indeed, it is the best of the deeds that a person does voluntarily.
As for the call to Islam, it is necessary that its condition be met: one must possess knowledge. Therefore, one should not engage in the call unless he has knowledge and clear insight into what he is calling to and what he is forbidding. He must have knowledge of the scriptural evidence and have studied jurisprudence in this matter. Only then does he act upon what he knows and calls to Allah (Mighty and Majestic), as He said: : Indeed, man is in loss, except for those who have believed and done righteous deeds and advised each other to truth and advised each other to patience. [Al-Asr]. So He arranged the matters in four ranks: the first is knowledge, which results in faith. When one learns what is obligatory upon him and what faith requires him to believe in—such as faith in Allah, His Messenger, and understanding of His religion—and he acts, he then calls after this. He said: , first: he learns and believes in what Allah has made obligatory upon him, he gains insight into it, and he acts upon what Allah has made obligatory upon him. Then he engages in the call to what he knows of the religion of Allah, and he advises his brothers to truth and patience in it.
