Always be yourself, unless you can be Jack Harkness, then always be Jack Harkness.
So i try to be. For me being Jack is not only to be in love with Ianto or to catch aliens. It's not enough to dress up in a greatcoat and to make a time vortex manipulator. But it is also a hard work. It is changes in temper. I should be able to look in his eyes and tell him that all will be all right. I must take the responsibility for everything i do, and i mustn't let someone underestimate me. I must be able to admit my mistakes and to fix it myself. I must forgive people however dull, stupid, aggressive and religious the most of them are. Sometimes it's hard to comport at this moments so i close my eyes and convince myself that it is just a new adventure in my infinite life.
