The term work life balance relates to a harmonious state where the demands of work and home life are in equilibrium. In other words, people with a good work life balance do not have too many demands in their personal life that impact negatively on their ability to perform well in their job. Equally, their work is not so demanding or stressful that they are not truly present for their loved ones or so busy that they never have time for them. Most people strive for a good balance between work and life even though it may see-saw from time-to-time. When a work life balance is out of kilter, people can feel very pressurised and, in the worst cases, it can even lead to developing certain mental health disorders for a time.
Happiness is one of those traits which is described as both a mental and emotional state. For example, you can mentally be happy at an event or for someone else while your overarching mood is sad. However, being happy is also an emotional state where we feel genuine joy coursing through us. It is often hard to capture happiness and to bottle it. However, the state can lead to higher levels of contentment, which is something that is more sustainable in the longer term. Of course, it is an entirely subjective matter, and what makes one person happy may be very different from how someone else might think about it.
To many people, the purpose of life is very clear. It has been laid out clearly either by their parents, teachers or religious leaders. For others, it is much harder to work out. In fact, many philosophers have argued for centuries about what the true purpose of life is. There is a distinction between what the purpose of any life is and what it means to an individual, of course. Some people believe they have found a purpose in their life if, for example, they do a job that they find fulfilling. To others, the purpose of all human life is to work towards a higher purpose that is bigger than any individual. Broadly speaking, the latter is a spiritual interpretation of a life's purpose.
