The phrase "zindagi mein khush rahena chahiye" translates to "one should aim to be happy in life." While it is true that happiness is a desirable state and everyone wants to experience it, it is not always possible or necessary to be happy all the time. Life is a journey that is full of ups and downs, and it is normal to experience a range of emotions such as joy, sadness, frustration, anger, and many others.

In fact, striving to be happy all the time can lead to a sense of pressure or unrealistic expectations, and this can actually have the opposite effect and lead to unhappiness. It is important to acknowledge and accept that life is not always easy and that there will be times when we experience difficulties and challenges.

Therefore, instead of solely focusing on being happy, it may be more realistic and beneficial to strive for a sense of balance and fulfillment in life. This can involve pursuing meaningful relationships, engaging in activities that bring joy and purpose, and finding ways to cope with challenges in a healthy and positive manner.

In summary, while happiness is an important aspect of life, it should not be the only goal. Embracing a full range of emotions and striving for a sense of balance and fulfillment can lead to a more fulfilling and satisfying life journey.
