Once you start writing (whether from lesson 1 or 20), a typical lesson plan is:

Review previous lesson. Read your previous writing, at least one copy of each passage, until fluent. (Make note of problems and learn them properly.)

Read each new word list until you're fluent, then copy each list until you're comfortable. (I've seen both 5x and "several lines of each word".)

Update your theory notes. (I keep a summary chart showing all the uses of each letter. The format changed as I learned more theory.)

Read each passage until you're fluent and then copy it until you're at your target speed. Do not try a passage without reading it first, until you've mastered the theory, I think after the 2nd book. You'll probably reinforce incorrect words. (This rule is also incentive to keep going!)

Books vary as to how fast and when to build speed. My Teeline text say to stay at 40 for all the theory, then build speed. My Forkner text says to reach 60 in the first lesson, then 80 fairly soon and stay there for the rest of the theory. Still others say to build gradually to about 65 by the end of the theory.

40 is fast enough that you're writing, not drawing. You can reach 40 or even 60 by copying the plates.
It's easier to build speed once you have good penmanship than to fix your penmanship after you build speed.

When speed building, your target speed should be 10wpm faster than your comfortable speed.

You can't reach high speeds in the early chapters. They have one letter per sound. Late chapters are more efficient. Some passages are easier than others. The brief form letters are a breeze!

When starting a new speed, start with a 1 minute passage, then build up to 5 minutes, then repeat for the next speed.

If you hit a speed block (and once you're ready to crank up the speed), try Swem's method. Take dictation at 10wpm faster than target, then again at 20wpm faster — and keep cranking the speed until your notes are "shattered". Get down something — anything — for each word. It stops hesitation and often shows areas you need to work on. When you're done, your target speed will seem slow.

Your last take of each passage should be slow enough to be perfect. That's the one our body will remember most. Perfect includes fluid writing, without hesitation.

If you're having trouble with an outline, write it with your finger about 6 inches high (in a tray of sand, or with a wet finger), then again on a wall with chalk about 12 or 18 inches high. Repeat with eyes closed to test. My son had occupational therapy for handwriting. Involving more muscles and textures and senses helps anchor the shape.

Write each problem outline until you can do it perfectly, then write it a few dozen times. This is called overlearning, and really helps.

I know it seems a waste of time to do one passage over and over and build vocabulary slowly, but it works. When kids learn to read, reading the same book over and over reinforces the vocabulary. Adding too many new words at once breaks the flow and comprehension. In shorthand, it leads to hesitation.

Hope this helps!
