I want the whole truth, what is being an engineer like?

I'm trying to decide if I really want to be an engineer before I go through the major struggle the math higher than Calculus and the physics are going to be. I'm interested in mechanical, agricultural, or computer engineering. I want to know all the pros, cons, and what the daily life is REALLY like for someone with this sort of job. Do they really get their hands on what they are building, or do they mostly just calculate things? Are the hours usually good or are they as bad as business jobs can be? Do you get to be creative and just brainstorm and build things that come to you? Or are you given a very specific task that you just do without any creative input? Any and all help will be appreciated! Thanks!
