In a social situation, it's easy to get caught up in excessive drinking
Most of us wish we could improve certain things about ourselves. Lasting change is difficult: Many of our habits are deeply ingrained, and certain core personality attributes may be immutable. But even the oldest of habits and character traits can be altered to varying degrees, as it's never too late to change; with effort and determination, it is possible to be the person you want to be.
Habit formation is the process by which new behaviors become automatic. If you instinctively reach for a cigarette the moment you wake up in the morning, you have a habit. By the same token, if you feel inclined to lace up your running shoes and hit the streets as soon as you get home, you've acquired a habit.
