In our youth, there's always an added sense of enthusiasm in whatever we do. So when a Muslim brother in his youth gives much time in learning the Deen and the ways of The Prophet (S) and the Sahaba (R), he becomes prepared to strive for the cause of Deen and go through any amount of hardship. The spirit of Islam drives away their sleep, they stay up each night in Salat, many fast regularly and keep themselves involved in Deeni works all day. Many young muslim brothers become so much enthusiastic that they lose all sorts of interest in worldly matters like studies, jobs, business, family affairs etc. But it's the Sunnah of The Beloved Prophet (S) to maintain a fine balance between all these things, not to abandon them totally. This can be clearly understood from a beautiful hadith from the Sahih Bukhari:
Anas ibn Malik Radiyallahu Anhu narrates that a group of three (men) came to the house of the wives of Rasulullah Sallallahu Alaihi wa Sallam asking about the worship of Allah by Nabi Sallallahu Alaihi wa Sallam. So when they were informed, it seemed less (than their expectation). They said: Where are we, compared to Rasulullah Sallallahu Alaihi wa Sallam when Allah has forgiven his past and future sins. So one of them said: As for me, I will offer Salat throughout the night forever, and another said: I will fast forever and I will not break my fast. And another said: I will forsake woman, never to marry. Then Rasulullah Sallallahu Alaihi wa Sallam came to them and said: Are you the ones who have said such and such? Behold. By Allah! Indeed I am the one who fears Allah most amongst you, and the most pious amongst you. Yet (is spite of that) I fast, and break fast, and offer Salat and I sleep (at night) and I marry women, so whoever turns away from my Sunnah is not from me! (Bukhari)
