Today.

Don't miss out on today because you are imagining that tomorrow will be "better" -Anonymous
I'm sure there are a lot of things that we would all like to change about our current  circumstances, but there are advantages, freedoms and joys that will be gone in life's next scene. 
So live for today and look forward to what tomorrow will bring. 
"The secret is Christ in me, no me in a different set of circumstances. The bigger story of our life begins at the moment we understand this truth. Life does not begin when you get married, land your dream job or board a plan to travel the world. It is found in the beautiful, powerful love of Christ, which changes us in the midst of all circumstances, especially the ones we find most difficult. We need only to be willing" -Elisabeth Elliot

Make plans. Look forward to the future. Be grateful and cherish today. Trust God. Hold onto His promises.
