Sorry Deks, I'm sure you're trying to look all original here but the fact is you do believe in things. Otherwise, you couldn't function.
I don't consider my way of thinking to be 'special'... merely different.
As for functioning without 'beliefs'... I seem to function just fine without ascribing to notions of 'belief' (in any shape or form) - as do many other people.
You are seemingly applying circular logic - because you apparently think 'belief' is integral to human existence, you cannot bring yourself to view life in any other context ('impossible' according to you for all intense and purposes)... therefore you keep ascribing the notion of 'belief' to others and their lives.
All valid for 'you' and probably helps you put it all into a frame of reference that you understand (which is practically no different than any other human when they stumble upon a possible 'unknown' and try to identify it by ascribing familiar things to it), but it doesn't mean you are accurate in your reasoning/interpretation/description.
Do you believe that the sun will rise tomorrow? Do you believe that you'll get paid for the work that you do on the job? Do you believe that you will probably survive driving today?
There are tons of possibilities (remote as some may be, while others are much easier to happen) that could occur which can (and on numerous occasions do) change 'expectations'.
The Earth could undergo a fundamental shift in its gravitational axis/forces, orbit around the sun, and a few more things (for reasons unknown, or well known) that could prevent my location from rotating into a position that would face the sun - probably unlikely to happen, but still possible.
I found myself in more than 1 situation where I wasn't paid for the work I did.
Any reason I should 'believe' I will get paid every time I do a job?
No point in doing that because I could easily be deluding myself (seeing how we don't live in a world that is 'fair' or cares for human well-being).
I might 'think' that I will get paid, but at the same time I keep an open mind to the possibility I might not - and like that, I'm prepared for other outcomes which are less likely to take me by surprise and I might be able to formulate a possible solution to a problem (again doesn't mean it will work, but its a possibility that could be considered).
Some of the time I volunteer (so why should I expect a monetary compensation or 'reward' for something like that?), and if I do professional work, there is no guarantee I'll get paid - the possibilities that can affect this very outcome are continuously present (therefore there are no guarantees - so what's the purpose of 'belief' exactly?).
I usually use my bicycle when I go out (I don't drive a car). The possibilities for accidents that could easily result in my death (or deaths of others) are effectively endless (which apparently have a tendency to occur on a daily basis in practically all areas of the planet to anyone).
Again, what's the purpose of 'belief' here?
I don't need it to 'live' or to 'survive the day', 'function', nor do I find the term of any relevance or even remotely applicable to my life.
There's a list of thousands of everyday things that you have to believe in to function. You have examined the evidence from the past and have concluded certain things that keep you alive and going every single day.
Actually, by examining past evidence I usually arrive at certain results/evidence (due to observation - which is an approximation), but I don't think of those results/evidence as the 'truth', 'the absolute' or something 'fixed' that I necessarily 'follow' or ascribe by - they are just possibilities.
Even if I initiate a course of action based on an arrived result, I still wouldn't consider that a 'belief' - merely that it 'might' be something to help me arrive at a decision, also always keeping in mind the prospect it could have been wrong, and be ready to discard it and adjust my actions accordingly.
Again... no need for 'belief'.
