The difference between persistence and quitting being the right choice is often a matter of timing, luck, and other subtle unknowable factors. As often as someone quits one thing to focus on something else, someone else sticks to their guns and perseveres.

Success is also often the result of many failures, not the opposite, which indicates quitting and learning is probably the more important skill as well.
