All SOLID principles point to the same message: avoid unnecessary complexity. The irony is that treating SOLID like strict commandments often produces the exact opposite.
The real secret is simpler. Write code you can understand at a glance. Code you can test fast. Code you can change without fear. Let the principles guide you, not cage you. They’re reminders, not sacred laws.
Einstein said it well: “Everything should be made as simple as possible, but not simpler.” If you keep that spirit, good design emerges almost by itself.
And that’s the whole point of software. Make it work. Make it clear. Don’t let theory drown you. Ants build giant colonies by doing small, simple tasks. We can build good systems the same way. Keep things small. Keep things simple. Let common sense lead.
