Compared to the entire universe, all life on earth is miniscule.
There are countless studies explaining this relativity, and they really put everybody’s individual problems into perspective.
Yeah, if your significant other breaks up with you or you fail a test that really sucks, but you are one of seven billion people in the world. Each and every person has problems of their own, all to varying degrees.
There are eight other planets in the solar system, and billions of solar systems in the galaxy, each with many planets. There are then over 100 billion galaxies in the universe. So really, earth, and people in particular, are quite insignificant.
Take a step back, and look at things from a different point of view. Immediate life is hectic and each problem seems magnified. Compared to the rest of the universe, however, what seems like the end of the world is actually an insanely small aspect of life. The universe is endless, and everybody and everything are small pieces that together, make it up.
