On opinions

In day-to-day interactions, keep your opinions and doctrines to yourself. Reserve your speech on your beliefs for your writing. Don’t delude yourself into thinking that your view is worth putting out there or involve yourself in petty arguments trying to prove that you’re right. Share selectively. This mindset will keep you out of conflict.

The best effect of being quiet is that others will want to hear what you have to say in the future because you have yet to insert yourself as they have. They’ll be more likely to listen because you’ve made your own opinion a scarce resource rather than a commodity, and now others will desire it rather than despise it.
