This post is one long moan. Of course startups are hard. So is marriage, and so is jogging. So if you're doing it, you'd better love it, because if you don't, you're going to be miserable. You do it because you love building things and love to learn things -- and you can handle failure, whether it's temporary or permanent. You can recognize that you have not actually failed if you've learned in the process, made personal connections, etc.
People doing startups need encouragement. They may need to be warned that this isn't easy, but they really don't need moans.
