> The findings may be explained by 'loss aversion', a cognitive bias that causes potential losses to be weighed more heavily than potential gains (the ratio is somewhere around 2:1, meaning that most people will feel comfortable with a decision only when the likely gains are double the likely losses). As a result, in situations where the benefits and drawbacks of making a change appear to be evenly matched, it may be sensible to take action.

This loss aversion ratio of 2:1 is an average or other. How do you find your own ratio? It's the only one that matters. I'm always switching tracks and on to the next new (or old and new to me) thing.

A better reason is most people toward the ends of their lives regret the things they didn't do, rarely any of the things they've done. Do more things. Change is good.
