This mentality is not uncommon on GFY, even amongst those who are doing well. Somehow people have associated my having a Saturn with me not having a good life.
The fact that I had a Thunderbird, a Mustang and an SUV means nothing, it's that I drive a Saturn now.
Apparently it's the status symbol value of your vehicle that determines your level of happiness. I save almost $800 in gas each year that I can put towards better investments and to my child's education. That makes me way happier than the mustang ever did.
If the vehicle you drive truly is a sign of happiness, then this guy must be down right miserable:

Don't base your happiness or success level on what you do or don't make, or do or don't have. I used to think I had everything I could ever want when I made way more money working for myself... but I was miserable because I was bored. I make less now, but I have 0 worries, no stress... I laugh with friends every single day and have what I consider to be a perfect family. I've gotten rid of the desires that people told me I should have to be happy... and obtained the needs and wants that are truly what makes me happy.
Find what truly makes you happy... and go with that, no matter what society, gfy jerks or anyone else tells that you are supposed to have.
What it boils down to is... don't worry about what others are doing, or what they say you have to do. Do what you want to do just because it's what you want to do.
