How to calm frustration and anger down?

Hi! Ive noticed and my family members have noticed that I’m quite a hothead when it comes to simple things. 
For instance while I’m cycling to work I could get frustrated at the fact the wind is blowing in my direction. 

I also use curse words quite a bit I stop myself from swearing when In front of children or I mouth it but don’t say it aloud. 

please help I want to stop getting angry and frustrated as I don’t wanna lose relationships because of it. 

I've started doing mindfulness at night like writing how my day went and how I feel but I need other suggestions.
