I've never changed the brake fluid on any car I've ever owned - that's around 15 or 20 cars over a period of over 40 years, everything from an Austin A40 to a Lotus Europa and a BMW 3.0 CSA. Unless you drive around like a lunatic, or there's reason to believe the fluid has been contaminated in some unusually serious way, it's completely unnecessary. If you do drive like a lunatic, changing your driving style would have a far greater effect on your survival prospects than changing your brake fluid.
The engine oil and the air and oil filters do need changing at the appropriate intervals, but you can do that yourself. If you don't know how, then learn. There are evening classes that will sort that out, and once you've acquired these skills you'll save yourself a fortune and evermore have the comfort of knowing that things have been done right. Don't forget - if a garage mechanic can learn how to do these things, then so can you. Same with the spark plugs and gearbox oil - change them at the required intervals, but learn how to do it yourself. In the meantime, get a friend to recommend a reliable local garage or look on Checkatrade. Don't go anywhere near Honda unless you're lucky enough to be a (very) eccentric millionaire.
As for the pollen filter, I usually wait till they reach their expiry date, then just take them out and throw them away. I don't bother putting a new one in - bit of an expensive and unnecessary luxury in my view.
Valve clearances? I sold my last Jazz (2003 SE CVT) at about 90000 miles. It had never ever had its valve clearances checked and it was fine. Ran as smoothly as a sewing machine. Frankly, it's such an awful job to do, the car would have to be rattling like a tin of bolts before I'd contemplate it.
Good luck!
