No, it is not wrong for a guy (or anyone, regardless of gender) to want to focus on his career before settling down and having kids. Choosing to prioritize one's career and personal development before starting a family is a valid and responsible decision.
People have different priorities and timelines in life, and it's essential to respect and understand individual choices. Focusing on one's career can have many benefits, including financial stability, personal growth, and the ability to provide a better life for future family members. It can also contribute to a more balanced and fulfilling family life in the long run.
It's important to note that there is no one-size-fits-all approach to life, and societal expectations and norms are continually evolving. As long as someone is honest with their potential partners about their priorities and plans, there's nothing wrong with delaying starting a family to pursue career goals. The key is open communication and mutual understanding with partners and loved ones.
Remember, everyone's life journey is unique, and individuals should make decisions that align with their values, aspirations, and circumstances.
