Can we be as selfless as Sikhi says and be successful in a world like today?

A Gurmukh can merge with Akal Purkh by following the Hukam of Akal Purkh with the help of Gurbani written in Guru Granth Sahib. However, there are few who put that much efforts.
ਰਾਮ ਸੰਤ ਮਹਿ ਭੇਦੁ ਕਿਛੁ ਨਾਹੀ ਏਕੁ ਜਨੁ ਕਈ ਮਹਿ ਲਾਖ ਕਰੋਰੀ ॥ – 208
Hence, we can be as selfless as Gurbani says. All the Guru Sahibs and many Sikhs have proved in the past history.
