Why bother?

I have long kept a journal of thoughts and it has served me well over the years, allowed me to review how my attitudes, aspiration and faith has evolved, dreams have been fulfilled or abandoned, as is the case. Why put it online? I guess its natural to want to share. Also, for the challenge to see whether I have anything worthwhile to share, anything that is true, anything that will resonate with others and hopefully encourage them. Or if not, perhaps holding up my thoughts to the inspection of others may reveal the fault in them, a fault from which I can be corrected. After all, I'd rather suffer the embarrassment of correction now to the eternal consequences of living in error.
