I am a type of person who see things in a different ways well most will fall to negative ones, pessimitic is what you called it. I overthink too much, but after that I see things in most spectular ways when before I'm on a side of negativity and then boom just like the bomb that explode, I cleary see all of these in appropriate ways it is like that I felt God  tapping me in my shoulder and say "Do not overthink things, have a patience in every struggles in life. Always think that there is more to life than that. Be happy as you can be. Just smile your best in that way." and yeah, just like that I feel relieved. I smile and laugh, I'm happy no matter what. Maybe, just maybe all optimist have a same attitude like mine. :)
