There's good conservatism and bad conservatism, just like there's good progressivism and bad progressivism. The latter consists mostly of change for change's sake, while bad conservatism consists of resisting change for no reason. But the good kind of conservatism is an important force in a society that has any sort of progressive energy (read: almost all of them) - it serves as a reminder of Chesterton's fence (that there is a reason (or reasons) why things are as they are, and you should understand those reasons before you change things).

I would not consider myself a conservative (though my kids perhaps would), but I consider that kind of conservatism important even if ultimately the change I want to see overrides it.
