is critical.

"The most difficult thing is the decision to act, the rest is merely tenacity." This line is saying that the hardest part of committing to an idea, process, etc. is the first step: acting upon it. After that, everything comes naturally.
"The fears are paper tigers. You can do anything you decide to do." Your fears may seem large to you, but they are really just harmless objects in the way of letting you progress in life.
"You can act to change and control your life; and the procedure, the process is its own reward." You are capable of changing your life and how it goes. Once you do this, the process of becoming a new you is a reward.
