What's a habit that changed your life?

I used to forget stuffs so letting everything noted helps me with money, dates, somebody's name, work, chess. Etc. What about you?

loving people

Well basically every single habit affects our life in any way that over time becomes significant, either in positiveor negative way

My life changed when I graduated from the music conservatory.

when I finally allow people to know about me instead of shutting people out

One on one connection with God.

Same but from university. Starting with health issues

Well that's right in fact there are people who has a lot of bad-habits like going to the supermarket hungry, using the credit card in installments or something so basic like not saying hello can impact in a negative way
