We play chord tones. Get some fake chord or lead sheet music and it will tell you the chord name. It's up to you to decide how much of that chord you want to put into your bass line, i.e. the root may be all you need or it could be the full chord tone (R-3-5-b7). Up to you. Ed's book gave you many possible bass line - time now to use some of them in your songs.
Going to give you something to jamm over. You decide how much of the chord to have in your bass line. Hint, the measures with two chords, in 4/4 time, each chord only has room for two notes, R-5 for both, perhaps R-3 for one and R-5 for the other. Perhaps just two roots on both - up to you. Point I'm trying to make is knowing how much of the chord tone to use is the next plateau. How much do you need to get the groove going..... in THIS song.
Have fun with Autumn Leaves.

Notice on this one your bass line is laid out for you with the standard notation bass clef.

If that is a little advanced try.

Practice time - get some jamming into your practice. Suggest one new song per week. Warm up with scales and your favorite bass line riffs. Here is a new one I'm working with now; R-3-5-6-8-6-5-3. Chromatic runs to the next chord is new and I'm still working to get all my choices in the keys I play in - to muscle memory. Chromatic runs - target the next root - miss it - and walk up or down to it. C to F -- you are on C go to D, Eb, E, F. With F to G - have to be creative here - you are on F go to C, F, F#, G, etc, etc.
How much time for warm up, scales, riffs, songs, etc? Going to leave that to you.
