Why is it hard to select fifth gear in my Toyota Yaris?

I have a 2010 Toyota Yaris diesel six-speed manual with 70,000 miles on the clock. It's now very hard to select fifth gear. Ive had the car six months with no other problems. Any ideas?
Get the gearbox oil changed. Toyota used a very light oil to reduce emissions and this is now getting old and degraded.
