The world has two kinds of people: one is able to calm people reluctant to proposed projects, from the difficulties will not be intimidated; the other is to miss an opportunity to move forward and backward between the wandering people. Know what to do ... ... I do not know if everyone is fully aware of their own.
I used to belong to the latter. Indeed, I have failed before, give up before, but as time goes by, I am not going back and forward between the two lingered, and I learned to choose forward or backward. Both forward and backward as you read in between the short of the one step away. Do you want to take every step to ensure their own right out?
I have been an opportunity lost. So mind extreme contradictions: a step back and take the opportunity to recover the lost come from? Or leave it and continue to look forward and do the rise? In fact, these two ideas are right, but the key is that your choice and your efforts. Although: " the water to flow" does not mean there is no representative of the time back. You can choose to go to the lost opportunity to find them again. Perhaps you may want to "now or never", since it has been lost, how could catching back? Would not a futile effort? But I wonder if you do not have the thought: That opportunity is specifically belong to me, others can not be easily taken away, so I catch it, it was me.
On the contrary, some people wanted to forget it, mistakes have been missed, and what will not find another opportunity, may this time really did not belong to me. ... ... In the end of the how to do? So hesitate. If so, why not move forward, you may've found a number of different, amazing things?
But if you move forward and backward direction of this loss are still hovering between a loss and can not advance and retreat, then you will get nothing. You missed that opportunity has become obsolete, but had the opportunity waiting for you in front of others, was again taken away, you will find it not very much loss?
People, must not be too rigid, to choose to move forward or backward. Maybe you can "kill two birds with" mean?
