@aboo_muadh You can gauge the acceptance of your worship on Laylat Al-Qadr by observing the extent to which you are able to refrain from disobeying Allāh.
Ibn al-Qayyim رحمه الله:
“Supplication is one of the most beneficial remedies, it is the enemy of affliction, it fends it off and treats it, obstructs its befalling and uplifts it if it descends.”
[The Disease & The Cure | Pg. 15]
