Depend on your current commitments. To succeed with each course you would have to commit about 30 minutes to each for about 30 days. That for most doesn't work, adding two new habits.

I recommend starting with one. You get to try Effortless success this week. Here

Abundance For Life is a great foundation course. What you learn in that course helps you get more out of any course in the future.

It doesn't matter which you do first, do the one that speaks to you. That's the one you're you'll complete and that's the completed course is the one that get the most from. The one on the shelf doesn't help you grow.
