The other option is lowering your expenses -- for example, working remotely in a city where your rent is much cheaper.
Unless your current spending is extremely reckless, cutting expenses typically makes less of an impact than increasing income. If you currently spend 60k, you cannot cut your expenses by more than 60k, but you can definitely increase your income by more than that if you manage your career properly.
But yes, remote work can be a great way to maximize happiness and savings (if it works for you, not everyone is happy with it).
