Tahajjud 

Remember, only those that chosen by Allah - In order to be the one, you'll have be it (wake up & perform your tahajud, Insya Allah)
That's the reason why 'Tahajud is like an arrow direct to the bullet', those Allah chose will be rewarded & will be answered soon or later.
But remember , when Allah blocked your wish , remember that Allah knows best. It might not be good for you, and you'll have so much better. Everything happens for a reason, to teach you lesson/ to make you the better person/ as a reward & etc.
what was destined for you, will find your way ❤️
