Are you good at running and climbing? If not, that doesn’t matter because those skills are unnecessary for this job! You will have to be fearless and skilled though. The job: remove all the dragons from the local area. The reward: a lifetime of fame and millions of whatever currency you choose, along with warriors to protect you from raids and a huge castle to live in. There is no reason not to do it, apart from the risk of dying from the dragon you may fight. But as long as you are skilled, that risk ceases to exist!
