It's easy to start a thing but to stick it out. I'm exactly the right person described above. Always,I make a plan to do something with a full sence of confidence, I believed I could keep the initial enthusiasm and get to the end finally, and no doubt I would  benefit from the original magnificent goal. But the actual routine is, I can control myself over the first day, mostly the second day, even the third day, but how about the next? I don't know how to answer you, because I'm guilty of the behavior what I have done.

Just like the saying, you can guess the beginning, but not the end.

I believe many people are confused by this trouble, even a lot of them are suffering from this painful torment. We can't say that things are supposed to look like this, that's an old and irksome excuse for coward. Dose that make you feel reassuring when you failing to do one simple thing? It's earier to keep back doing nothing, but things are always there waiting for you. You can't escape, even when you bypass the block, the block will stand in the center of the road you are going to go through.

In that case, the only way is to give up the idea of escape, but to meet it courageously. The more blocks you beat it, the  wider road you are going to have.
