Entrepreneurs and especially wantrapreneurs are addicted to learning. When classes and books are consumed because the knowledge will be valuable "someday," it's just-in-case learning.
Courses taken that we execute on and produce right away are just-in-time learning. We learn and do simultaneously.
The problem is just-in-case learning can become counter-productive.
There is nothing wrong with learning purely for the love of learning. It's a great gift.
However, if the idea is to start and grow something, every minute spent reading and taking in new information, if not used immediately, is a waste of the most precious resource, time. When starting out time needs to be spent producing.
Producing can be creating leads, setting up systems, creating content or otherwise doing work that gets us closer to revenue generating activities.
If you're about to start a new training ask yourself if this is something you can implement right away. If it's not, but you still want to do it because you'll enjoy the experience, then, by all means, do the training.
But know that when you're doing just-in-case learning, put it in the fun and entertainment bucket because listening to videos is leisure.
Doing exercises and sharing the results (just-in-time training) is work. And it's work that propels starting something great.
