5. Literacy and numeracy skills

The oldest and most necessary skills are literacy and numeracy. Traditional education and schooling are based on these two abilities. You might be surprised to find out how many grown-up people have difficulties with literacy and numeracy skills at work. However, keep in mind that all employers require them and expect their workers to be good at dealing with multiple forms and documents as well as keeping correspondence with customers and clients. The more developed your literacy and numeracy will be, the more job offers and better employers you will have in your professional life.
