This Thursday is my 28th birthday!  I think we all assume we're going to live a long life but in reality, we have no idea what's in store for us.  Honestly, I try not to set too many goals for myself (unless they're from God).  Instead I try to focus on what steps God would have me take each day, who He'd have me reach out to others and how I should manage the resources He's given me.  I may not always get it right but this is what I aim for.

James 4 says

"13 Look here, you who say, “Today or tomorrow we are going to a certain town and will stay there a year. We will do business there and make a profit.” 14 How do you know what your life will be like tomorrow? Your life is like the morning fog—it’s here a little while, then it’s gone. 15 What you ought to say is, “If the Lord wants us to, we will live and do this or that.” 16 Otherwise you are boasting about your own plans, and all such boasting is evil."

I think it's ok to look at the big picture once in a while as long as we seek God's will in doing so.  I guess birthdays always make you think about the past, present and future and I hope I become more faithful to Him with each new year!
