If you are grasshopper you should be aware of the time it took him to walk on rice paper without leaving a foot print.
Joking apart I was advised to do about 10 mins every day. Keep improving daily. Also don't expect to be perfect the first time just keep going. A walking foot will do quiet a lot of gentle curves. My friend and myself both take foot pedal out and go with the stop go button and sometimes forget to lower feed dogs.
Watch as many videos and read as much as possible and practice drawing on paper with it at 90* to paper and just train your mind to the pattern any time of day or night.
Ps I always go nearly to beginning after a gap in quilting.
