Once you realise buying 'stuff' and experiences doesn't fix anything any more you will start yourself down a path of self-improvement which IMO is the only way to feel content. It just so happens that this goes hand in hand with mustachianism.
Try learning new skills or hobbies such as cycling, walking/hiking, swimming or whatever sports you feel you can access easily, fix things yourself, make new friends, take up extra activities outside of work that will help you move up the ladder and closer to early retirement. Most of these things will expose you to new people and new ideas and with your new hobbies and home improvement projects (on a shoestring budget of course), you will find quickly that there is no time to feel 'bored'.
I find these little projects take up almost all of my spare time and feel like I am living life with a purpose, as apposed to being annoyed that there is nothing on TV on a Friday evening. While I can stomach an hour or two of TV at the end of a long weak, I found depending on TV or spending to go on nights with friends out or eating out left me feeling hollow as while these are fun at the time, the good times can't go on forever and they were setting me back financially.
Take pride in what you can achieve in these new hobbies/skills, and while you will not be an expert overnight, you may indeed find that that these activities opens up new streams of income, or is just a good way spend your free time. Remember though, family comes first! As long as you have good realtionships, you have no reason to feel down and out! If you're relationships aren't working out, well you might need to work on those too!
