"Diagnose problems to get at their root causes."
Don't jump to conclusions.
Instead, take your time, think for a while, and figure out the real issue. Often this will be a second, third, or fourth-order cause.
Next, find a solution. You'll need to figure out if this is a problem that's fixable through effort or if it's one that requires assistance to overcome.
If you're able to fix it, fix it. If not, ask for help. Either way, execute the plan and solve the problem.
