You have to divide your time. Perhaps 50% of your drawing time should be about learning new drawing techniques and putting them into practice. The other 50% of your time should be working on finished drawings. Finished drawings of a subject matter that you love.
If you only learn new techniques and constantly practice you never will create a finished portfolio of original work. All of your drawing will be about practicing a drawing technique. Does that makes sense?
So yes practice, but not 100% of the time.
