Time and circumstances help us to achieve our goals, but we have to do what must be done.
Sometimes we say, "I can do it later", but later can be too late! If you have an insight, an inspiration, a feeling that you should get up and do something, do it! Tomorrow you may not be around or, you may be and may realize how many opportunities you have been missing in life.
Think about that. No... don't just think... do it!
