Great response! Reframing the problem is an especially important and well-known technique in applied mathematics and physics. And the others can arguably be generalized into "solve the easiest part first". If the easiest part is at the bottom, start at the bottom; if it's at the top, start at the top. Keep solving the easiest part remaining until there's nothing left to solve. This inherently requires breaking the problem into achievable sub problems.
