No. I believe stuff happens. Example. Eight years ago on my birthday, I was supposed to go to a birthday party my friends were having for ME. I was in a great mood. It was a beautiful day. Got into the car. It didn't start.

Called AAA. The guy came and couldn't fix the problem there so gave me a tow to my repair shop.
I called the hostess of my party to tell her what happened. The repairs took quite a while and I got hungry so went to a pizzeria across the street for a slice while I waited. Hours later I showed up at my party, exhausted. Everybody had eaten and I had nothing.
They day was a crashing disappointment. It wasn't negative thinking. I'd like to believe in the LOA ( law of attraction ) but I just can't because sometimes no matter how upbeat your thinking is, bad things happen. They just do.
