The Chovos Halvovos explains 3 reasons why most people are not so happy in this world :
1 - they are always looking for more , thus they miss the great benefits that surround them.
2- they get used to so much they fail to appreciate it.
3 - there are some things which seem negative & it takes wisdom to realize the benefits.
This is why Hashem invented miracles to wake us up !!
How does this apply to Chanuka ?
Now may be a good time for a gem of Torah study.
