Intermittent Bedroom Light

My ceiling light went out in my bedroom. At first I thought it was just a bad bulb, but then it would turn on and off on its own. I tried replacing the bulb and nothing worked. I tried replacing the switch. The first couple of times I tried it the light didn't go on, then it blinked like it did before, then it would turn on whenever I turned the switch. The next day it wouldn't come on, but after a few tries it eventually did.

Here's some information. Other lights and receptacles are on the same circuit and I don't have any problems. Is it safe to assume it's not a problem with my circuit breaker?

If the light comes on, even if intermittently, is it safe to assume the wire between the switch and the light is alright? If there was a short, the light shouldn't work at all right?

The light fixture is about 7 years old. I read somewhere that the socket may be bad (something about the center pin getting pushed in too much from overtightening lightbulbs), but there are two sockets and I think it's unlikely that both sockets are bad. Another suggested that the wiring to the sockets could have come lose, but again it wouldn't likely be to both. I can't imagine how the wiring could come lose on a ceiling fixture, but I suppose it's possible.

I'd appreciate any advice or things to try short of hiring an electrician or destroying my walls.

There are three light switches. I'm not even sure what the other two go to. I think originally there may have been a ceiling fan. If they are bad, could it affect the third switch, which I did replace already?

Yes, they are backstabbed. Perhaps I will re-replace with the ones to screw on instead. I assume I can get single pole for those as well?

Thank you everyone for the information. I'll start by replacing all three but with the screw-type connections. Then I'll take out the fixture and check those leads. Since it is intermittent, the lose connection seems to be the most reasonable explanation rather than a bad wire. I'll keep my fingers crossed that it does the trick.
