Thanks for the advice. Your suggestions are great. One thing I know I struggle with is talking about it. I just feel like 99% of people would be like "everyone hates their job - get over it." "Just put your 40 in and get to the weekend", etc. I can definitely say I've stayed in my job out of fear - fear of change and fear of the unknown. Thanks for the book recommendations - will check out for sure. Glad to hear thing are going well for you - thanks for sharing your story!
have definitely seen that before and it's so unhelpful.
it sounds like you have a good life outside of work - just lack of stimulation in your current role. We recently had someone in an interview say the same thing about wanting to work more on something they could see the direct results of. In their current role (this was for a change within the company) they began a process that would be handed off to someone else to finish. They wanted that beginning to end responsibility. In the end we were not able to give them the position, but did make it so part of their time would be involvement in a new project that they could have more control over. If your company values you, they'll want to work with you on this.
To me it sounds like job hunting isn't a bad idea. There's nothing wrong with going and doing some interviews to see what's out there. And just because you interview doesn't mean you have to leave or say yes to an offer. But it sounds like it's worth testing the waters for you.
