It's a well known fact that comparison is a killer - jealousy also.
I am very VERY blessed to be someone with extreme focus and with very little care regarding what others feel I should "achieve" - people set themselves these ridiculous "goals" - okay, so you achieve goal #1 - NOW what? Goal #2! Okay, you reach that... NOW WHAT? It's insane. Live your life and enjoy who YOU are - I've never understood people who compare me to other people or who get jealous over things or friends.. WHY DO THAT? It's utterly illogical - I am happy with who *I* am, and looking at lots of the folks people "aspire to be like", I am EXTREMELY thankful that I have no such desire, ever EVER. I have many, many faults and quirks - but WE ALL DO. Another way people make the mistake of envying others' lives is through "social" media (which is anything BUT social) - people build a "stage set" and dress themselves up, carefully curating and picking the "Showreel" to show to you, whilst ALL the crappy, horrible parts - the lies they tell, the messy hair days, the fights they have with loved ones... well they NEVER show THOSE parts - it's all a distorted ILLUSION - don't ever compare yourself to anyone, ESPECIALLY not to "perfect" people - why do you think they aim to polish the LIE of this "perfection"? Yup, INSECURITY, and because ALL of us are anything BUT perfect, and FB just exaggerates that illusion even more.
I look at my family and friends and I am glad they are doing what they are doing, but, just as a suit may fit my friend but doesn't fit me, ALL our lives are different - and looking at many of my friends, as lovely as they are, I cannot imagine ANYTHING more tedious and unchallenging than being them or doing what they do, let alone be "jealous" of them OR what they have. They have achieved much, and are amazing people, but I ain't them, I am me, and I am blessed to have what God gave ME, it wouldn't work for me to "be" them or have their stuff, that's THEIR life, and good for them, I'm over the moon for them - it's called being secure in yourself and knowing your own personal strengths and weaknesses, and without God's love or blessing, NONE of us would be anything, period.
So, yeah, comparing yourself to others is foolhardy in the extreme, and a VERY foolish thing to do.
