First, make sure your shoes are tied. Wouldn't want to trip and fall, would you?!
Then, put one foot in front of the other.
Simple. See, it's easy. You know how to do it. You've just forgotten.
Everybody loses sight of the important things every once in a while. Just get back on track, put one foot in front of the other and walk. The best part is, you don't have to walk fast to get where you're going. Feel free to take baby steps.
