So this is something a lot of us have struggled with and I think it happens when your goals aren't aligned with your work.
So what are your goals right now out of work? What is your workview and your lifeview. Find the intersection between those to get a good idea of what you want to accomplish in your life.
After coming up with those, try and tabulate the things you do at work where you have the most energy and the stuff you do at work that engages you the most. Hopefully, there are things in that list that give you some energy or engagement. If there is, do more of that and tell your manager to help you move towards doing more of that work. If there isn't, ask yourself what you want to learn. If you can't learn that on your current team, switch to a position/team where you can learn that. If your company can't provide you with those opportunities, then it might be time to find something new.
Startups are super rewarding but there are many unknowns and you have to do a lot of vetting to find the right ones. Even then, you could be wrong. If your goal is to start a company, then it might be the right route to go.
TLDR: Try and understand your goals in life and what you enjoy doing day to day before jumping ship to a startup. Your safety net will allow you to do that :)
I don't know why your comment is being downvoted. This is the usually the root of work frustrations I have seen people have (including in startups).
If your goal is to achieve public acclaim And recognition, you will do things differently vs. say a goal of work on intellectually stimulating things vs. say controlling the decisions in a company. I have a colleague who once got a kick out being the one to sign the cheques of major celebrities who endorse our brands and you'll have a different kind of career path if that's your goal vs. say the kicks a financial trader gets.
Problems usually happen with job satisfaction when either goals aren't clear or you're optimizing towards conflicting goals.
