Learn new things. Getting a higher education can bolster your self-esteem and interest in the world. But it's not for everyone and it's not the only solution. Reading, traveling, taking fun classes, attending guest lectures, and meeting people from other cultures will do the same thing. Or try MOOCs––massive online open courses––these courses offer very stimulating ways of stretching your knowledge and abilities, in your own time. Ultimately, instead of running from new experiences, engage in them, and seek more whenever you can. After all, you only live once.
