The social pressure to "be interesting" is one of the factors that I think leads to a lot of our collective misery. I think the problem is one of scale - if you're not engaging with other people because they don't share your interests, you may be hanging out with the wrong people, but you may not have a choice. You may be required to hang out with them because they are co-workers, neighbors, etc. - members of communities to which you may belong but may not have willingly chosen (i.e. if you're lucky enough to have been able to choose your job and your position and the team you work with, you are in a very fortunate minority).

So much of our self worth is wrapped up in "being important" or "being interesting". We don't ask the question enough, "To whom"? As someone else mentioned here, you should be important to the communities you have explicitly chosen and built - your wife and kids, the friends you choose to keep in your life, etc. If they find you interesting and important, that really ought to be enough for just about all of us. I do feel like an awful lot of this pressure to be interesting stems from people who have not cultivated such communities of choice and are left with a dire need to feel important to anyone who will pay attention to them. It's a sickness that I think a lot of people have been able to muster into the wrong kind of attention building, which makes it seems better than it is (e.g. parasocial relationships through social media, etc.)

All of this is to say: Are you happy? Do the people who matter to you find you interesting and fun to be around? Focus on them and be happy. Our lives are enriched by the people we let into them. So long as everyone in our circles are well fed, well loved, and well rested - ourselves included - we can find peace and happiness. Excitement means different things to different people - you'll never catch me bungee jumping, but I get a rush when a delicious meal I had planned turns out exactly as I intended. Find what excites you, surround yourself with people who love and appreciate you - and whom you love and appreciate in return - and work toward your own sense of happiness without the judgement of the chattering classes.
