Definitely true in my case.
2011: Paid $390/week by BMP in Los Angeles. Rent was $750/month. Starving and 10 pounds underweight.
2016–2017: Comfortable financially, not living paycheck to paycheck. CrossFit, eating 3600 calories a day, working out five times a week. Trying my best to not annoy the absolute hell out of my friends spamming workout pictures/videos.
But, definitely gotten “Wow, you seem to be doing so well” that seems to tie economic and personal well-being together.
