This is so true and (strangely) incredibly empowering.
If it’s within your control, you can change it. Push toward the solution long enough and it will be so.
But that’s generally where great ideas really spring from => not the high level concept that is just words/ thought in your head but the real world struggle to bring the reality of it to life. Each flawed step forward that is your fault turns into a “taken for granted” step that someone on your team put in the work to solve!
