Matchbox in my pocket...

Inspired from Muhammad Ali (boxer)'s idea. Living in a sinful world, where its almost impossible to stay away from evil deeds. So now, i always keep a match box in my pocket. If I feel like committing sin, looking at a girl with a bad intention, feel like lying, swearing, hurting someone or anything like that, I burn a match stick and put it on my skin. It feels like Ooooh....that hurts, and then comes a thought im my mind, how would I feel when my whole body would be burning in the fire of hell (infinite times hotter in intensity) for committing such sins. It certainly is not worth it. May Allah ta'ala save us all from sins and lead us on the right path. I have realised that there is no use of committing a sin. We commit sins to cheer ourselves, to enjoy, to make us feel great, to make us feel happy but on the other hand our creater gets really angry. We make big claims like, we can do this for Allah, we can sacrifice for Islam, bla , bla, we dont really mean it. We claim to be strong, but in my eyez this is not power, power is when you stare at a girl's body and immediately lower your gaze for Allah's sake, power is when you feed a hungry, power is to forgive and ask for forgiveness from others., power is when you are capable of doing something bad but you overcome n control your nafs. I admit i had little bad habits in me, that had become my routine e.g short temper. But then i started to keep a match box or a lighter in my pocket, whenever i craved or felt like im about to lie, swear, lose my temper, etc i thought of hell's fire and the matches in my pocket.
