There is no perfect time to start.
Preparation has its place
and you have prepared enough
the lesson plan
the rough sketches
all of the skill-building and training
Now it is time to get in the game
It is time to learn by doing
If you don't do anything
for fear of doing it wrong
then you will never get it right.
Get into communication with the people you want to serve
learn from the feedback
adjust your course as you travel towards the goal
Just take the next step
do it now
