Danger of not having snow tyres

I am usually a very responsible person and I never do anything if I did not have the time to think about it. I do not like to hesitate and I have to be sure about things, thus, I am very accurate and I demand the same from the people I know. However, even though I am a level-headed person, I have my ups and downs as well. This is what bothers me because I would like to make those drawbacks disappear and I cannot because those drawbacks are basically created by the fact that I am so accurate and I have think about stuff for a long time. This winter I had this kind of a problem because I had lots of stuff to do at work and I was constantly occupied with work, and I could not think of anything else. I ended up thinking like a maniac about my job and stuff that had to be done to a point where it started to get annoying. I basically annoyed myself because I could not deal with stuff like normal people do. I was constantly thinking things over and over because I wanted them to be perfect. It got to a point where I forgot to change tyres in my car and I did not use snow tyres for the whole winter. I did not think about the danger of not having snow tyres on my car. All I thought about was my job. This could have ended really bad and now while I am thinking about it, I decided to change myself.
