I’ve never been a ‘go-getter’ so I can not advise you how to develop that. Rather, I am going to suggest that you contemplate why your attitude and behavior shifted after the birth of your child. Many perceive the ‘go-getter’ persona to be self-absorbed and perhaps reckless at times by focusing on a career goal and aggressively doing whatever it takes to achieve it, without considering the impact on their personal lives or what happens next after the goal is achieved or what happens if the goal is unachievable.
With the birth of a child, many people experience a shift in perspective and priorities, since you now have a human being to whom you are fully accountable and for whom you are fully responsible for at least 18 years. The kid didn’t ask to be born, and so it be hooves the parents to make that child’s development and week-being a priority. Parenting is a 24/7 career whether you stay at home or have a paying job. I was a single mother, so I am speaking from experience. Even if you have a great relationship with the other parent and all are under the same roof, the child is priority #1, the family unit is priority #2, and your career comes after.
This reshifting of priorities isn’t easy when someone has been career-driven, and being successful in one’s career does benefit the child and family not only by providing income, but also if it provides the parent with a sense of fulfillment. Therefore, it is necessary to find a balance between family and career, and also to include family in the process of balancing. Have you discussed your dilemma with your partner? If you’re feeling uneasy about work situations, it does carry over into the home life in some way – even if only because you are preoccupied with your situation. Let the family in and explain what’s troubling you – they may not have answers, but at least this will give them some insight so they know that your discontent is not because of something in the home situation. On the other hand, they might surprise you with some insight, because hopefully your partner knows you better than anyone.
Heck, this listlessness may even just be a result of brain fog if your sleep patterns have changed and especially if sleep is disrupted by the baby. Regardless, I hope I’ve offered some food for thought.
