What a wonderful story here! You definitely generated 150 swelling hearts for these children, I'm very glad that there are people like this who do this!
Bad days are definitely learning days. We learn from them and reflect but we don't dwell. Dwelling is unhealthy!
The saying here goes that if you can help one then it's great, but if you can help ten then it's even better.
When a difficult task ends successfully one can sleep so much better.
To dwell is a very unhealthy habit, as it brings with it regret and negativity. Someone sang; "yesterday is dead and gone and tomorrow is out of sight"
A good reminder to focus on the present.
