Replying to Staying consistent with tricks

My biggest problem with progressing is that it seems like I have alot of tricks but when I try them again after not doing them for like 2 days I can't do them (especially on rails). Some days I just can't get any tricks. I know everyone has bad days but my bad days happen so often it gets annoying. I will stomp a trick 20 times and the next day I'll try it 20 times and won't be able to get it. Anybody have tips or comments on staying more consistent with tricks?
