I always look at other peoples and think "I think I should re design and start again" its always the case with me. Its even worse when I finish a design then don't like it because I've messed with it so much.
I get this all the time, only this time I've actually given in and gone for it, business cards and stationery are being printed as I write this and my new website should be up and running soon.
Good advice from tim, I took quite a while doing my new stuff and I'm still loving it all as much as when I first came up with the ideas, despite looking a loads of nice work that could sway me in to trying something else so I should be ok for a while now
Happens to me all the time. My current site is the only one I've ever had up for more than 6 months. I am getting sick of it now though, but this time I think I'm just going to realign and improve on it instead of going for a whole new design. Just need to find the time...
