Thoughts from High Level to Low Level

When I try to program in C nowadays, my minds has to do some effort to think it in low level. In Python you only think about the algorithm in the light of the abstract features of the language. But in C, you need to consider a lot more aspects e.g. memory. As my practice changed from C to Python, I sometimes just cannot think in Low Level, sometimes it is just a mental inertia, sometimes it is just the lack of practice.
