Pascha, each stage of your life brings different types of fullfillment and different avodah you can complete.
You think being married means you can serve Hashem with everything?
Most men I know (right wing and left wing) have more trouble getting to minyan when they are married. Why? Becuase they have more responsibilities. They have a wife who might be sick or kids…and less flexibility than being single or learning in yeshiva. Most women with young kids find it harder and harder to daven as they have more kids. These are just two basic examples.
What happens if you don’t get married? Or you can’t have kids? What then? It doesn’t matter WHAT your goal is – it could be a career path or a goal to perform as much chesed as possible. But you should have something for YOU, independant of others.
