I am not convinced that you can change your personality just like that. In fact, I find it striking how little people change their core traits. However, people can learn to live with them, and I think it is the idea here.
You don't become more extroverted, but you can improve your social skills.
You don't become less neurotic, but you can learn to manage stress, or just avoid stressful situations altogether with proper planning.
You don't become more agreeable, but you can learn to become more considerate.
You don't become more conscientious, but you can make a framework to complete your tasks: schedules, checklists, etc...
You don't become more open, but you can educate yourself on opposing viewpoints.
Also understand that the "big 5" are not stats to maximize, while some traits are linked to success, they all have downsides. Extroverts and people high in agreeableness tend to follow the group even when it is wrong, lacking personal judgment. People low in neuroticism can get themselves into trouble because they didn't consider the negative consequences of their choices. Conscientious people can be rigid and obsessive, and there is such a thing as being too open (are you open to murder?).
The idea is: don't change your personality, you will probably fail anyways, but make the best of what you have, by making small adjustments. Ultimately, I think it is what the article suggests, once you take away the "big 5 scoring" bit.
