In the past, most people had only one job. However, recently more and more people have more than one job at the same time. In my opinion, the main reason for this is that people are in a bad financial situation or have bigger goals for a better career.
First of all, some people say that working two jobs is not difficult, and could even be more procuctive. In my opinion, this might actually be more of a characteristic feature or these are habits learned from parents as a traditonal.
Nowadays, most people rightly complain about receiving low salaries. Not only low wages, but also rising living costs are a problem. One of the biggest reasons for this is that the laws do not sufficiently protect workers. As a result, people started working in other organisations to meet their daily living costs.
On the other hand, you could develop your different job skills and could earn more money, you could as a result have many networks, these networks could be new big opportunities or new partnerships for the future. On the contary, you may encounter some failures if you do not control it effectively, and also you could face some healt issues. Overwork can sometimes affect us more than we realize, some physically and some psychologically.
Finally, we need to establish the right work-life balance and proceed in a planned manned. Therefore, people should simply ask themselves this question, should I work to live, or should I live to work?
