Your general happiness is predisposed. You can have bursts of happiness and depression, but your overall level is usually around the same thing. So if you go through life thinking "well i'll be happy as soon as..." then you're probably wrong. It will make you happy for a little while, but eventually you'll go back to your general happiness level.
And those levels are unrelated to your job, social status, weight, etc. It’s more of your outlook on life that will impact your overall level. There are two types of thought about learning that impacts if you’re a happy person or not. The fixed mindset says that you are only as smart as you are, you aren’t capable of getting smarter. Mistakes are mistakes. Those with the growth mindset believe that mistakes are learning tools, and if you try hard enough, you will be able to become smarter and you can accomplish anything as long as you really want it and you’re willing to work hard to get it. I personally believe that most people go back and forth between the two of those mindsets. But studies show that those with the growth mindset tend to have happier dispositions than those with the fixed mindset.
So there you go, beebees. If you are a happy person, you will be able to enjoy your relationship at the current stage and if you can’t do that, then marriage won’t fix it in the long run…. You’re just a general unpleasant person.
