Life is a lot more fragile than we think. So you should treat others in a way that leaves no regrets. Fairly, and if possible, sincerely.
Unfortunately, the clock is ticking, the hours are going by. The past increases, the future recedes. Possibilities decreasing, regrets mounting.
But who can say what's best? That's why you need to grab whatever chance you have of happiness where you find it, and not worry about other people too much. My experience tells me that we get no more than two or three such chances in a life time, and if we let them go, we regret it for the rest of our lives.
Instead of things I'm good at, it might be faster to list the things I can't do. I can't cook or clean the house. My room's a mess, and I'm always losing things. I love music, but I can't sing a note. I'm clumsy and can barely sew a stitch. My sense of direction is the pits, and I can't tell left from right half the time. When I get angry, I tend to break things. Plates and pencils, alarm clocks. Later on I regret it, but at the time I can't help myself. I have no money in the bank. I'm bashful for no reason, and I have hardly any friends to speak of.
