Memories represent your past, and your dreams represent your future. The wisdom of this quote is that you should always have more planned for your future than what you’ve accomplished in the past. Getting nostalgic is one thing, but if you get to the point where you feel like your best days are behind you it can get pretty boring and desolate. Always have a dream to be working towards rather than sitting around thinking of the yesterdays gone by. Memories are still cherishable, but shouldn’t be your point of focus.
