What do you need to do to be of benefit to others?
Master a craft?
A better position?
Those are all things you can do. Get started.
What about being less busy, less distracted?
Dealing with your own hesitation or fear?
Being more available or attentive?
All things you can work on. Get started.
What if you are feeling inadequate?
What if you are not good enough?
Then you need to learn to sit with yourself. Be patient and listen.
Once you can do that for yourself, you can do it for others.
