That other person who got that job put time into it and achieved it. Good for them.
Someone lost a shit ton of weight and looks ripped. That's motivation for me to lift too and eat better.
It comes down to you, are you using that as fuel to motivate you or are you seething inside and burning with envy?
I honestly believe that envy is the thief of joy and if you allow it to consume you it will destroy you.
The only people that turn me off are those folks who make political shit posts, but I don't follow them.
