It is hard indeed and it is a good quote.

Talking of change, it looks like your vote isn't worth much but you upvote your comment. I am not against this so much for small accounts but here is something to consider if you comment on my posts. I often give 1 perent votes (currently 6c) but, sometimes more. Sometimes I use it to push a comment to the top. However, if someone has self voted, it means it that it will push their comment to the top, which I may not want, which means I don't vote at all. I will vote on this but it is something for you to consider as it is likely that my vote is more valuable to you than your own vote. Voting on comments is a very powerful tool in my opinion.
