>> stupid shit like getting into more debt
>> The more money u earn, the more money u spend, the more stress u have
The key to more happiness for anyone who is not dirt poor is to live with the means of someone 1-3 tax brackets below. If you make $100k/year, live as though you only make $60-70k. If you make $300k, live like you make $120k. It really is that simple. Stop trying to attain the "next lifestyle bracket", because it will NEVER "be enough". You will be miserable your entire life, trying to scrape your way to the "next level". "Unfulfilling" does not begin to describe that path.
I used to pay $1300/month rent, with a $700/month car financing, a $120 internet package, etc. I now live in a cheaper neighborhood with $640 rent, gave up the car (ie: $0/month financing), with $40 internet, etc. I went from $40k in debt and $0 savings account 3 years ago to $0 debt and 5-digit savings today. The difference in quality of life that makes on a day-to-day basis is enormous.
Forget the white picket fence and the $50k+ car. Nobody gives a crap where you live or what you drive - including yourself, whether you believe that or not. Live somewhere with great public transit or, if you really need - not want - a car, buy used for $500-$2,000 that gets you from point A to point B. Stop trying to impress people with your lifesteal. Live cheap, and use the incredible amount of disposable income to lead a happier life.
