Need To Smell Good And Tolerable.The difference between having deodorant on and not having it on is huge. My dad always tell me that you might not notice your body odor but others will. In my job, I get to serve customers through a check out lane at a grocery store and I even I can tell who's been using deodorant and who doesn't. Now, there are good brands of deodorant and some half decent ones but I won't touch on that (I don't want to sound like an ad). I do know the difference and when I was a teen, I completely underestimate the power of hygiene as I was lacking that back in the day, I used to skip baths to every other day and it does notice when I am smelly, especially after a day in gym when the sweat makes the odors come out and it won't be pleasure at all. LOL! I learned my lesson as an adult as my hygiene is much better to be tolerable around people but I have done foolish things to. A few times, I even forgot to use deodorant after a shower and I still smell even after I was clean.
Moral of this story: DON'T FORGET THE DEODORANT
It shouldn't matter the type of deodorant that you use (I used the spray on type) but be sure to use it. People will like you more.
