Every person is a possibility. Every person is many possibilities.
There are different paths you can take, different journeys you can loose yourself into, different decisions to make. The person you are today is probably not the person you will be tomorrow and certainly only one of the many different persons you could have become.
In this wealth of options, you can end up moving from one to the next. Or you can make an intentional choice, stick with it, and always keep in mind a couple of principles: this is what’s better for me and this is what’s better for the people I care about.
