Fusing Two Fields

It is great to start another intellectual journey at the middle age. In the past, the majority of the theoretical engagement seemed to lack a sense of hands-on-ness. In contrast, current learning seems to focus more on solving concrete problem. Instead of discarding the past experience, I would like to compare the two and form unique perspectives riding on both fields. Fusing the two, but not confusing the current as the past one, is important. In the end, my identity will be more from the current discipline than from the previous one. What rhetorical strategies to use to well-poise such a tension is important.
