How can I improve my Te as an INFJ?

Hi everyone, as the question says i wanna know can i improve my Te??

It drives me crazy, i love to organise my tasks with schedules but the thing is i cannot commit to them for long term, only the first week and i don’t get the tasks done effectively. When i compare my way of doing things to people with Te (whom i really jealous of) i end up disappointed in myself i feel like i am incompetent to do things the right way.

Also, i want to be efficient, i want the schedules i make to be efficient to get my tasks done EFFECTIVELY.
I have a busy months ahead of me so i reallyyyyy want to be prepared for it. I have a lot of things and tasks that i want to do but i need an effective way to do them. Can anyone help me with that? Like if u figured how to develop your Te can u share it please? Thank you all
