When sharing an advice, I phrase it with an emphasis on my person, such as: "in situation X, I personally do Y", or "something that works for me is X".
It can still be an advice, in the sense that I may be sharing some lessons learnt, but without the patronizing tone that you describe (which I also find really annoying to deal with).
