Here are a couple links which I hope can help you a little.

The first video gives some great advice on confidence building things to sketch, such as cool rock formations, trees, etc. The take away is that natural subjects such as these allow for more imperfections than say a sleek new sports car, which would be a very advanced subject.
The second link is a bit lengthy, but it explains what drawing from memory is, and the difficulties that arise. For example if you say wanted to draw a dragon with wings from memory you would need to first draw studies of how wings work, scale patterns on reptiles, joints in animals etc. Memory drawing complex subjects requires alot of understanding not just of the act of drawing, but also how things work in reality. So at this point sketch what ever you want to sketch but use reference - either photographic or a physical object.
Also one thing to understand about motivation is that it has peaks and valleys. To boost our motivation it is very helpful to have an emotional reason/ answer to the question "Why do I want to learn to draw?". An emotional reason will be much stronger than a logical reason.
I hope some of this was useful!
Good luck! Live long and prosper!
