If you do anything with a expectation of praise, you are likely to be disappointed. But you should still want to do praiseworthy things.
You ought not reject the urge to do something (in the context of positive intention), only because it might lead to embarrassment. You can think it over, though. That's what embarrassment is for. If it still seems right, revel in the possibility of embarrassment. You might be surprised by lavish praise.
