According to dozens of montages I watched, that girl wakes up early, workout, eats well, excels in her job, relationship, and takes care of herself. It seems good, right?

It's good but people don't just wake up and start excelling in jobs, relationships and life in general.

Honestly, I think no one has it "all together", no one is perfect so while we dream about that beautiful lifestyle and work towards it, we should also have in mind that we're not perfect and we shouldn't be hard on ourselves trying to achieve what the people that set the trend don't even have. Life is for living and living should be fun (our personal definition of fun).
