"My current thinking" is a great way to start sentences.

My current thinking is (where you're at).

My current thinking is (fearlessly say it even though you're not 100% sure). 

It leaves space for development, improvement, refinement, nuance, and just... mistakes.

We often want to nail down, define, box in, or limit a concept. It's all in the name of wanting to understand something well, and that place is a good place to start.

However, in order shake up your field of expertise, it's beneficial to hold your thinking lightly. If a better frame or more cogent idea comes along, you can update your current thinking.
