This is a great point. It's important to be mindful of the path dependence you are creating for your future self. At any point in time, I think you can roughly bucket problems into three categories: 1. This is a blocking issue now. 2. This is not a block issue now, but postponing will cause more pain than we would save by not doing it now. 3. This is not a blocking issue and doesn't create future pain. The third bucket are natural to postpone. Finding the balance between the first two is one of the primary challenges of engineering.
