It's fleeting. What makes you happy today might feel miserable tomorrow. You need to recognize this and be willing to change.
It's hard. Life is hard.
It's hard. Life is hard.
Not to get too philosophical, but I honestly don't think that things make people happy or unhappy. Happiness appears to be a choice. I say this based on my observation that I've known people who've lived in objectively awful circumstance, but were genuinely happy -- and I've known people who've lived in ideal circumstances, but were miserable.
