I wish. Page design is one of those things where you can feel like an expert when looking at someone else's page, but as soon as you attempt it yourself, you end up making a mess and filling the page with all your own personal pet peeves.

I think the best advice is probably to start as simple as possible: no more than two columns with responsiveness to one column, no more than a few colors, etc.

But also, I wouldn't be too hard on yourself comparing to this site. Someone spent a lot of money on a three letter domain, and they probably spent some more on the design for it.
