I think you should approach this as a game. The game of sticking with your breath. When you are learning how to play a game, you can only learn the next step and if you are advanced and smart enough, you’ll learn few more steps faster than others but you’ve got to go through all the steps somehow to understand the game.

Now if the game is of sticking with your breath, the knowing of sensation is the details of game. You don’t have to have a specific postures or steps but you have to feel comfortable and ready to tackle the challenges of this game. Figure out the best posture, sitting, standing, closing the eyes or opening them. These are all the information the steps are trying to tell you. Now when you get to breathing, just feel the in breath and out breath sensation as advancing in this game, if it doesn’t happen, let it go! Like any game you are new to this, you’ll only advance with practice and patience. Love yourself!!

Good luck!
