The biggest hurdle to overcome when wanting to switch jobs, for me and for all the people I know, is going through the interview process.
This isn't the sort of discussion you're looking for.
But I'd say for most people who are bored at work, working on a CRUD app in a startup isn't going to be intellectually stimulating.

Its incredibly time consuming and can also be quite stressful and dehumanizing, as you'll be leaving a lot of interview rooms thinking you're an imposter when the process is just awful.
How so? Most interview processes focus on finding folks who can solve totally arbitrary algorithmic questions that aren't used anywhere other than "Algorithms 401" at University.
While there are a handful of HN users that seem to gravitate toward that being a useful skill worth filtering for, the prevalent attitude seems to feel that it's outdated and asinine.
