Customize your code for your needs
I look at every day as an opportunity to improve myself not just on new years. If you’re into improving systems (Such as using DevOps) then why not improve the most important system you have…Yourself.
James Clear has written in my opinion a clear and practical way of changing your habits by working on a system of habits in his book Atomic Habits. Instead of having a resolutions such as “I will lose 500 pounds by the end of the year” or “I will make $1,000,000 a year” which are for the most part impossible goals since you don’t have the systems of habits needed to not only reach the goal but to support it in the long run.
