I'm going to ignore a construction workers instructions
Why would you ignore their instructions?
Only a concerned person would do a good job.
Following instructions can be time consuming but it is not good to ignore the instructions of experts. It could be dangerous to ignore the people who know better.
I just want to see what's going to happen. I think it'll be fun even if it doesn't go well.
I don't think that's wise. You could really injure yourself if you aren't careful.
