Tips for practicing output?

I had a more than 1 hour long conversation with a normal person completely in Spanish this weekend. When it was over I felt good about myself. But later when I started thinking about how it went I felt discouraged.

I know I often butchered the grammar. My active vocabulary was lacking. I had to skip explaining certain things because I didn't know how to. But sure, she understood me most of the time.

Since I haven't practiced much output, I know this is to be expected. I don't have the time and energy to practice much either, but I feel I should start incorporating a small amount.

What exercise would you add for output if you want something that takes a maximum of 15 min per day?

• Practice thinking in Spanish?
• Having AI tell you what to write about, and write a few sentences and let it correct you?
• Writing a diary?

Please, come with suggestions or personal experiences.
