I can do this

I wanto to learn this

This isn't important for me

I can choose a task (type) that I already know in order achieve my goal.

I can choose an unknown task (type) in order to achieve my goal (for example, a task which was recommended to me).

I can change an existing task (for example, from a textbook) so as to achieve my goal. For example, instead of writing down answers to questions in a listening comprehension task, I can give an oral summary.

I can set myself a task based on authentic material in order to achieve my goal, for example splitting up a text and then piecing it together again in the right order, or making a gap-fill exercise.
