There is a road and there is fog ahead, all you know is that you have to keep going and sometime just let things happen to you.
The wisest thing to do when you cannot interfere with the circumstances is to keep calm. A long long time ago a Sri-Lankian bookstore owner, brother of a parliament delegate who came to Romania, gave me a simple Buddhist book: "How to live without fear and worry". The main idea is that we should not fear nor worry when confronted to a problem. Because if there is anything in our power to change the circumstances, then why worrying, we should just start acting. If there is nothing we can do, worrying wouldn't help anyway.
I am a type of control freak, I like to plan ahead of time and tend to worry and get anxious if plans change and things happen in a different way. It doesn't mean that I am not spontaneous, but I tend to hope that things will happen the way I imagine them and I get disappointed when reality doesn't match my imagination and high hopes. This leaves little place for the unexpected, so every news that may have a negative impact puzzles and paralyze me with fear. Every time this happens I have to learn to deal with it, overcome my worrying and the fear and keep living the present moment as if those news never came, at least until their threat becomes a concrete evidence.
After a few days of agonizing anxiety my heart finally found the answer: let it happen, let everything happen, accept it, let it flow through you, then you'll see what needs to be done, without getting too much involved. Keep detached. Accept, with great serenity and light at heart. And the road will unfold, although the fog won't let you see the end of it.
