"Maybe I am lazy but if you are shooting a wedding or a really important event you have to take a lot of photos and you have to edit every single photo, I don't really do this, but I pick like 50-100 pictures which are the best and edit them.
If it's not under/overexposed and you set the right whitebalance then I won't edit it unless it's worth to do it "

You know, there's a massive reason that wedding photographers get paid THOUSANDS of dollars. Most of the work is done outside of the wedding. You've got planning, meeting, etc. But you've got to realize how much post work goes into a wedding. I've talked to many pros and they say that 75-80% of the time spent on a wedding job is done in post editing. Photographers don't get paid $2000-$10000 for going to a wedding and "Clicking a button" all day then calling it good lol.

this. be sure to have a nice portfolio set for them to look at. that portfolio determines whether your hired or not. you need have excellent people skills.

Do your homework and lawyer up before ever even considering doing a wedding. (Unless you're a second shooter, then the liability is on the contracted photographer) There are so many legal things with shooting a wedding that people don't even know about or look past. There are photographers out there who have been sued for hundreds of thousands of dollars, and even some in prison just over unhappy customers.
