After a discussion with Andrew. One thing can change a person's life, one sketch , one drawing, one painting, one project can make a career.
Actors or musicians, one performance can make them into a superstar. On the other hand one performance can also ruin a career. But its also possible to make a comeback. One year, one month, one week can make a difference.
Best is even after one great song the artist has another and another, consistency of talent is valuable.
one joke , or one hello can start a new relationship,
one accident can change a whole life,
one chance meeting in an elevator or random location can change the direction of your life.
Anything is possible...what you think about most is what you will become, is what will happen.
