The thing is that Hindus will only give it the large when in a significant majority and as soon as the numbers turn against them they pretty much give up. The only exception I've seen to this is the Tamil Hindus of Sri Lanka.
They also have appalling unity, did the Punjabi, Tamil, Nepali Hindus come to help the Gujaratis? Nope. Yet you had Arabs and Somalians helping the Indian muslims and Pakistanis.
Sikhs historically have always been a minority in India and even greater Punjab so we are used to fighting when the numbers are against us. Just look at how we retaliated against the muslims of UP who heavily outnumber us when they tried to take our land. Even in Hyderabad Sikhs have fought against Muslims who make up a huge amount of the city.
The recommended schedule for Sikhs is to go sleep saying God's name and wake up doing the same:
ਸਉਦੇ ਵਾਹੁ ਵਾਹੁ ਉਚਰਹਿ ਉਠਦੇ ਭੀ ਵਾਹੁ ਕਰੇਨਿ ॥
saudē vāh vāh ucharah uthadē bhī vāh karēn .
Whilst going to sleep they utter Lord's glories and praises and when awake they eulogise Him as well.
ਨਾਨਕ ਤੇ ਮੁਖ ਉਜਲੇ ਜਿ ਨਿਤ ਉਠਿ ਸੰਮਾਲੇਨਿ ॥੧॥
nānak tē mukh ujalē j nit uth sanmālēn .1.
Nanak bright are the faces of those who daily arise early and remember God. p312
You have to sleep the same number of hours anyway. So why not go to sleep early and wake up early? Afterwards, you'll still have the same number of hours to study--there are only 24 hours in a day.
If you say it's the same if you do Amrit Vela first and then go to sleep, it's not: If you do it your way, after you wake up, you won't be worshipping, as commanded above. Instead, you'll head to school or whatever.
We're supposed to worship after waking:
ਗੁਰ ਸਤਿਗੁਰ ਕਾ ਜੋ ਸਿਖੁ ਅਖਾਏ ਸੁ ਭਲਕੇ ਉਠਿ ਹਰਿ ਨਾਮੁ ਧਿਆਵੈ ॥
gur satigur kā jō sikh akhāē s bhalakē uth har nām dhiāvai .
He, who calls himself a Sikh of the Great True Guru, should rise early and meditate on God's Name. p305
Meditate after you rise, Gurbani says.
