6) Career Mobility

Portability" means your skills work anywhere, not just at your current desk.

• Avoid becoming an expert in Internal Tools (software only your current company uses). Instead, master Industry Standards like AWS, Python, Salesforce, or SQL.
• Look at 5 job postings from other companies. If you can do 80% of what they are asking for, your skills are portable. If you only know how to do things "the company way," you are in a dangerous position if you ever get laid off.
