One day, your heart will stop beating, and you will wake up in the darkness of the grave.
On that day, none of your future plans, worries, or fears will matter. All that will matter is how you lived this life. It is absolutely your choice whether you wish to waste this life drowning in ignorance or lead it purposefully as a journey towards Jannah. On that day, you will be shown what your own hands have earned, and it will be too late to regret.
So start now, strive for it, and prepare yourself for that day.
You are responsible for it.
