A GPS works best when you know where you're going. I tried saying "take me somewhere good" just to see what would happen. It said "location not found" Life works in a very similar way. You can't just want a "good" life, you have to define "good" and set goals.
I have made physical vision boards before and I have to search the internet anyway for the pictures I want, so making the Pinterest version seemed very logical. The key is to look at this board again from time to time and remember why you chose those images in the first place. Pull it up in front of you when you review your calendar and to do list for the week, Make it happen!
