Who is responsible?

I just have realized I am responsible for all the things that happened in my life including the incidents that made me happy and also the incidents made me to cry. But there is one thing that I couldn’t understand yet which is why the hell I always forget this simple philosophy and at most times not realizing this logic. Also another truth is we are the only ones who are making opportunities or threats and even fates. This is the time to realize that mind is the barely best tool that determining the hells and paradises. I don’t believe in another life. We all get only one and precious opportunity to live in this earth. So it becomes necessary to make it happy. Every single action that happens around us makes at least a threshold amount of ‘effect’ inside us. Most times we blame the environment for the bad things happened in our lives. But actually ask yourself why a specific incident happened. Is it because of the environment only? Or is there at least a percentage of contribution of you in that action? I am pretty sure you will have at least a small percentage of contribution for things that happened in your life. But I know you may doubt the suitability of this argument at all situations. If a natural disaster took place in your area and because of it, you have lost your relations, and then the blame definitely goes to the environment. But remember most of the natural disasters take place due to the humans’ activities and because of their unconcerned behaviours on environment. So here you might not be responsible but a cluster of persons become responsible who you may know or even not know. We decide our own fates and sometimes others’. If you used to drive your car following the road rules then you save both your’s and others’ lives. But if it is other way round then the fate is also get modified.
