I'm the second child of 3 and two years younger than my older sister. Right up until the end of middle school and most of high school, my sister was the "gifted" one and constantly lauded by my parents for being very mature and wise beyond her years. I was the problem-child that hated homework and chores, loved violent video games that my mother abhorred, was constantly being lectured by my dad for how lazy I was and how I was wasting my potential. My mom was extremely frustrated with me for not doing as well in school as my gifted sister and took me to multiple psychiatrists and tested for ADD and ADHD multiple times (I didn't have either). My sister recieved a car for her 16th birthday from our grandmother and my parents told me point-blank that I was get a car only when I paid for every penny of it myself (to be fair our grandmother didn't buy a car for my sister. She was just getting too old to drive right around the time my sister turned 16). My sister always had her own bedroom while I shared a room with my younger brother until I was 16, and even then my room was considered the "spare" that would be used to host exchange students for weeks or months at a time while I was forced back into my brother's bedroom, even after my sister left for college because she had too much stuff to take with her and my parents refused to throw out any of it.

Fast-forward a dozen or so years and I'm 25 while my sister is 27. I graduated from a college on multiple national top-ten lists with a bachelor's degree in Economics and not a dime of student debt, living on my own and earning $70,000 a year. I drive a $30,000 sedan and next year I will have saved enough to buy my $50,000 dream car without trading in my first. I also bench-press ~200 lbs and can run a mile in less than 7 minutes.

My sister, on the other hand, got a "Media Arts" degree from a very generic college, worked part-time minimum wage jobs for a year after graduating, before quitting and moving in with our parents again. Dad got her a full time job at his company, but she had to quit that job after a few months because of a mental break-down (that coincided with the last Presidential Election) and health issues. She's still living at home, still driving our now-passed grandmother's 25-year-old car that is literally falling apart, and working on a master's degree in anthropology, which I suspect will lead to about as many employement opportunities as a "Media Arts" bachelor's degree.
