“The only difference between those who have failed and those who have succeeded lies in the difference of their habits. Good habits are the key to success. Bad habits are the unlocked door to failure. Thus, the first law I will obey, which precedeth all others is-‘form good habits and become their slaves. ”

-Og Mandino

What I think that this statement means is that you should go to the path that will lead you in the right direction not the path that will lead you to the failure. Follow the success not the door with there is failure because you have to succeed as the person that you are not the person that you’re not.
