Quick decision
Start with fit and work structure before reading facts and next steps.
How to Decide Whether This Career Fits You
Work-structure tolerance
Can you sustain diagnosis, repair, preventive maintenance, tool use, documentation, and customer coordination over repeated work cycles?
Fit depends more on daily work structure than on the attractiveness of the title.
Evidence and accuracy tolerance
Can you work carefully when facts, records, tools, safety, or stakeholder expectations matter?
Many career failures come from underestimating documentation, quality, and accountability.
Feedback and pressure tolerance
Can you handle correction, deadlines, service pressure, or operational uncertainty without losing reliability?
The issue is not whether pressure exists, but whether you can recover and improve.
Long-term path tolerance
Can you build adjacent skills, credentials, tools, or portfolio evidence over time?
Career resilience usually comes from transferable skills, not one title alone.
Career profile
Read the definition, responsibilities, and context together instead of judging by title alone.
