There are a few reasons it could be happening so I'll start with some the most common
If your switches are dimmer switches and you're not using dimmer bulbs they burn out faster
If your light fixtures are sealed you need to get bulbs that are compatible with sealed fixtures
Make sure you're getting quality bulbs as lower quality bulbs will die faster
If your area has less than stable power your bulbs will burn out faster, though higher quality dimmer compatible bulbs will handle the less stable power better (you don't need a dimmer compatible light fixture to use dimmer bulbs)
I use GE Reveal HD+ bulbs in my fixtures (basic apartment sealed domes) and they just keep on keeping on and they're really color accurate.
I started with store brand LED bulbs and they just kept burning out and the color accuracy would be best described as vague at best. Not to mention they'd burn out pretty much every year when the storms would roll in and my power would get flaky.
