how many ways are there to improve my endurance

School, credit and now job, for what it's worth.

Won't be easy using the job points to boost it though, the best job for endurance is athletic, giving 0.09 dev points per job points. In other word, you will need 2000 job points to get from lvl 5 to 6. Or if you prefer, 20000 job points for 18 to 19
