If people focused as much energy on being DETERMINED to be happy as they do on being DETERMINED to be offended (on purpose), and focused on making others happy 10x more than they do on focusing INWARD at their own "problems", then noone here would BE angry, you'd just shrug and say "Ah welll, never mind - I've lived without it this far, and I can wait a bit longer", you'd all have a nice surprise to look forward to, because you'd be getting on with the rest of life, you know?
Patience and kindness maketh a man, not shouting and stamping like a toddler. Not only does that lose you your inner peace, it ALSO affects other people, which is really selfish indeed.
