It does not matter how much or long you have trained, studied or experienced, there is always more to learn and space to grow.
You can’t grow or learn if your cup is full.
From my own experience in working with energy, clients or even martial arts, learning and experience never stops.
New challenges arise whether internally or externally and it may take a skill set you have yet to develop.
To call yourself an expert, could limit your growth, if you have the mindset that you know everything.
There are people in my life who I deem as “experts” in their field, yet they tell me they still have a lot to learn.
When you seek help from a professional, it’s good to know how they approach their work, do they claim to know everything and solve every problem?
Do they use the same cookie cutter set of methods from when they first started?
Always, always ask questions before you work with someone.
