The most difficult step is always the first one. Although you are going to face many difficulties and other obstacles in the way of progress, all of these problems start with the first step and this is your will that takes the first step. Getting out of your comfort zone in every aspect of your life means the willingness to face those obstacles.
There is poetry from Hafez about that:
There is no way to the realm of wisdom for slothful people
A man of action would welcome the problems flame instead of staying crude*
*Translating poetry is always difficult, especially when it comes to Hafez
