So basically that's the main formula...Pray pray pray. That's it.

Ramadan is regarded as the phase where you can literally RESTART your journey towards Allah azza wa jal. 20 precious days of Ramdan passed and we noticed that since the devil was tied up in knots, it wasn't him urging us to listen to songs but Our Own NAFS is Our Greatest enemy. So cleanse your nafs and make it your friend. As they say, " If you keep reminding your heart about Allah, One day your heart will start reminding you about him azza wa jal all by itself. 

Try to avoid worldly and useless activities. And spend most of your time in prayers and supplications.
