Since many countries won’t permit you to enter if you have fewer than 6 months validity remaining, it was time to renew my (first!) passport. The first one treated me well, granting me entry into 44 different countries.
Guinea Bissau, Senegal
Taiwan, Senegal, South Korea, Sweden, Norway
Japan, China, Peru
South Korea, UAE, Kazakhstan
Should be interesting to see how the next 10 years turns out.
