Time

There are always these "Sometimes" in your life when you have to decide between somethings. It may be smaller decisions or bigger. Sometimes there will be a guiding hand pointing towards a direction sometimes there won't be, first we think that taking decisions on our own is very hard thing to do, but taking decisions is just a trailer the hardest thing comes after taking the decision when you are only left with two choices 
1. Do It.
  Or
2. Chicken Out
trust me both are very difficult. 

There are also two effects to both the points.
1. Do It & you fail.
  Or
2. Chicken Out & you incur a great loss.

But don't worry these things will only happen when you take the decision so cheer up, but there is also another possibility that the decision you made is entirely wrong, but you won't know it until & unless you DO IT or Chicken Out.

You must be wondering WTF is he trying to say??  What  I am trying to say here is that no matter how hard you try to make happy living there always will be something bothering you inside. 
If you take the Leap & lands successfully on the other side it proves your ability, but if you fall & still you crawl back up & did it successfully it proves that you are a great human being. After all no one knows what is going to happen in future so take the risk the worse thing that can happen is that you DIE, but again who knows!!!
