My lesson

Want is the toughest enemy of all
but Regret is also worse than the sin
Carefulness helps, or tortures
Hope kills
Doubts are sometimes unnecessary
Smiles are mortal
Observation is preparing
Lying always hurts
There's no such thing as enough Wisdom
There are always 2 Sides
Caring and Thanking heals some
There is never Useless
...
Lotsa things suck
Others, luckily, are why-life-worths-living Delight
