I don't share my opinions on the internet any more, or at least try to avoid it. That's what my friends are for. I don't finding it a rewarding experience, and I find the prevalence of other people sharing their opinions online to generally make the experience worse for me.
I will however share my experience, what I have done, how I did it, how it worked, how it failed, how I choose the live my life, and why I make those choices. But these are not opinions, rather they are facts about me. People can do with those facts what they wish. If people disagree, well that hardly matters because these are my choices not theirs.
