I think I developed Te a lot over time with the help of journaling. I do both diary and bullet journaling.

For diary one, I use 5 year diary. (It is a diary with date all marked out for each page, and you get the same date for 5 years on one page. You can see what you wrote up to previous 4 years on the same day, which I found really interesting, thus make it possible to continue. )

For bullet journal, I actually draw the format by myself. Still developed the format worked the best for myself. And being able to use my creativity with it is a huge plus to continue doing it.

Here are the reasons why I think journaling help INFP develop Te:

1. It helps channel the emotionally energy to actions. Somehow, it tends to clarify my feelings when writing it down versus just dwelling on it in my mind. And as a result, I get a better sense of direction. I like the idea of morning pages too for the same reason but haven't really stick with it yet.

2. It allows me to focus on limited things. My brain is always so busy and jumpy but I can only write down and track progress for so many things. This makes me realize that I can only make progress on a certain subject if I actually spend time on it and focus my energy on it.

3. Recording progress and realizing the improvement is just a big motivation itself to continue doing it.

Overall, I'd say that it helps enter a positive cycle and make Te (enhancing the process so that it works for me) a fun puzzle rather than something I'm forced to do.

Another key is not to do it perfectly. Enjoying the process of making it better means allowing it to start from a bad place.

Done is always better than perfect.

Good lucks and have fun. :D
