What is too long of a commute? I might have a good job opportunity but it is an 1 hr and 45 commute one way. I will have the option to change after 3 months, 1 or 2 days a week. Is it still worth it?

If it's a good job with good pay and a chance for advancement then I wouldn't worry about the commute and take it. Any good job is worth it. Out here, there are many people who commute from the Valley to the Bay Area daily because of their jobs. Jobs aren't easy to get anymore, so if it was me, I would jump on it. Besides , the long drive will help wake you up in the morning and when you get home at night, it will feel that much better! Go get that job !
