Words of advice, as just that: advice.

Talk is easy ....for the poster of that blog article link that started this thread.

Sure, I cultivate optimism, at times, I think because I numb myself for some very drastic/sad things that have happened in past 12 months.

For myself, a better route is not to pretend or think I will be continuously optimistic, just to be at peace and more contemplative. This is good enough for me, because I can move to the "happier" state or just allow myself to feel sad.
