There's always someone who travels to expensive, exotic locations for holidays;
There's always that certain someone who holds a higher rank than you in the rat cage. That same person may also be younger than you;
There's always someone who has more qualifications and certifications than you'd ever achieve in your lifetime;
There's also probably someone who saves more than you;
There's someone who has reached financial independence quicker than you;
For everything that you do, there's always someone who's better, faster, smarter in a spectrum of different things.
And that's perfectly fine.
"Comparison, a great teacher once told me, is the cardinal sin of modern life. It traps us in a game that we can't win. Once we define ourselves in terms of others, we lose the freedom to shape our own lives." - James C. Collins
