Time for a new website.
What are your goals?
What's your budget?
Who is going to help you?
Find someone to help you with this project. That might mean a professional, or it might mean a friend. If you're hiring someone, ask around for recommendations. Read this Mike Monteiro article on how to pick a good designer. You want somebody who gets you, and you want somebody who isn't afraid to tell you no. Remember how I said a website costs from zero to one billion dollars? You want somebody who can keep you safely in your range, who can look to the future and who can gently guide you back to those goals.
If you're not hiring a professional, there's still no reason to go it alone. Recruit a friend to give you feedback. (Or develop an informal advisory board.) Maybe you know someone who is also itching to redesign their site--have work dates together! If you're using SquareSpace or Weebly, use their support desk--that's why it's there! Even as a professional web designer, I call on other experts when I am stuck on a problem. (And, as with all feedback, remember your goals and only take in the feedback that works towards those goals. Trust yourself.)
That's it. Not so hard, right? Of course, you could write a book on each, but that's a good place to get started.
