Not only is smoking bad for your health and you waste a lot of money. You also waste a ton of time to care for your smoking habits. I quit smoking a week ago and it never felt so enriching before. Getting older feels like getting more busy, having to do more and more shit.
My employer allows me to smoke during work time which never made me think of wasting a lot of time because I never had to track smoking time. While quitting I realized more than ever (I had attempts to quit before) that I could spend a lot more time at work doing productive stuff. Not only at work but even at home I'm gaining ability to focus because I don't get interrupted by addiction of smoking kicking in every hour.
