How can a Muslim obligate himself to persevere in prayer (congregational and individual), and prevent himself from committing immoralities such as looking at non-mahram women and its destructive consequences?

Striving to elevate oneself and discipline the soul towards goodness is a great deed and a sign of embarking on the path of guidance, for Allah Almighty says: "And those who strive for Us – We will surely guide them to Our ways. And indeed, Allah is with the doers of good," and the Prophet, peace and blessings be upon him, said: "And the Mujahid is he who strives against his own self in obedience to Allah." The self is like an infant: if you neglect it, it will grow up loving breastfeeding; but if you wean it, it will be weaned.
