how to practice correctly

This article which i have linked to at the bottom seems to contradict itself. It seems to be saying that the way vipassana is taught where you note what comes to your attention is incorrect. Im finding it confusing as I am trying to get clear about my practice but different people seem to say different things. I am getting to a point with Buddhism where I dont know who to listen to anymore and wait before you say "listen to yourself" I have been trying that for years and not really progressing hence the reason I am looking for some more clarity and riding such articles. My question is how do I figure out if I am practicing correctly? Some people even say that there is no such thing as "incorrect" meditation "**if one continually tries but cannot establish mindfulness on breathing, then he can practise other kinds of meditation for the time being.**" but then goes on to say "**Most of the meditation practices that have become popular today are not in line with the Dhamma. Those practices are to note in your mind, “pain, pain”, when you feel pain in some part of your body during meditation, and this they say is vedananupassana – contemplation on feeling. If your mind goes somewhere, they say to note “going, going”, and this they say is cittanupassana – the contemplation of mind. If you feel sleepy, they say to note “sleepy, sleepy”. And, if a desire or agitation presents itself in the mind, they say to note “desire, desire”, or “agitation, agitation”, and this they say is dhammanupassana – the contemplation of mind objects. Those are the incorrect practices today that people are being taught as meditation.**" http://mahamevnawa.lk/ananda-sutta-leading-to-awakening/
