With the economy and politics in their usual mess, I am curious. Do you worry about the future? Why? Why not?
"Conquer fear and you conquer life" (Alexander the Great) Worry is all fear based.Giving in to fear will make you afraid to take risks.Take risks,if you fail then try again.If you succeed then teach others how you conquered your fears. Eventually you will feel invincable and believe me....that is a liberating feeling.
Do not about that,I used to do bad on physics,i hate to work on that things. but there are lots of ways you can choose to be your bright further. Nothing is more important than your attitude for the life.
