I wish I had a quick answer, but I know that our dwindling attention span makes it more and more difficult to "stay with it." If we don't see instant results, we assume we won't ever see any. As a follow-up to my previous post about beating the clock, this is an enormous challenge.
It's why marketing is so difficult. You don't really know if you're spreading the word as effectively as you can. You're not sure your message is getting out there quickly enough, or if you even have the right message.
The secret is having the confidence that you're right, that your diet or marketing plan is on the right track. It requires more time, not less.
So, when you're tempted to throw in the towel, ask yourself if you still believe in your plan or vision. If you do, hang in there. Give it some more time. Success might be just around the corner.
