"把一切抗在自己的肩上" is great!
But "坚定地相信：人定胜天" is arrogant. Do as much as you can, and let it be. Probably, studying some psychology is more useful than joining a colt. Indeed, most scientists are not religious now days.
Just to let you know, most priests study psychology in schools so that they can help others more effectively. And probably, that's why their speeches are so persuasive and helpful.
I personally believe that you can acquire most things that religion can offer you through learning. For example, the biggest benefit in religion is faith, which gives you strength, then build faith in yourself, in humanity, in love, .... Or, religion helps people to face the frustration better, then study psychology and learn the right way to remove anxiety and convert pressure to ambition. I think you can gain more by learning it scientifically than taking some tools (mixed with bless and curse) for granted.
