What 3 things do you worry about most in photography?

The 3 things that i worry about most in photography is blur because sometimes when you or we take pictures our hands our shaking or sometimes our hands our wet and make our hands shake and sometimes our balance in our body because sometimes our body shake same as our hands too.Come out ugly because when our too excited to take that picture it might come out ugly or we just need too take pictures everyday in our life.Come out like blur on the other side and good in the other side and if that happened i have to take pictures all over and over again. it might be black out or to white for the photo like when your taking photo outside and the sun, the person that your taking might be white on the outcome.And one thing is that it might be exposed and come out not good as like i wanted to be. And the picture might be blur when your taking picture that's why i need the stand for camera. one thing that worried me is blur and the angel or how the picture will look good. and make the picture not shaking as my hands shake every time i take picture.
