Rules are only as good as your discipline to follow them.
After 11 losers in a row (most people lose discipline after 3 losers in a row) or a few months of break even trading (where your equity curve is range bound) you will be very tempted to change your rules.
When things are going well, yes there is nothing to do (why would anyone be tempted to give up on rules that are printing money?)
But when things aren't going well, there is still plenty of do, you have to maintain focus and discipline to stick to your rules and only change them if are very sure they dont work anymore.
