is it annoying because it's a wiser and more mature attitude? is being negative the only way to socialize and be "relatable" with others?<<< I guess so, but there are many people who will find you inspiring
If you have a positive attitude and see the good things in life, you will live in the abundance and not in the insufficiency. You will have a healthy heart, and that is one of the most important things in life.
Your greatest weapon against stress and negativity is your ability to choose one thought over another. Happiness escapes from those who refuse to see the good in what they have. When life gives you every reason to be negative, think positive.
