Many times I've been thinking about what the key to successful learning is and I'm convinced that it is strong will. Will stands at the origin of every action, including learning. Will makes you take the first actual step. And the second one. And the third one. Strong and lasting will makes you take enough steps to eventually learn what you need.
If you have the right reason, you will want to learn. More importantly, you will want to learn long enough. If you want to learn Chinese because you like Chinese food, you do not have the right reason. If you want to learn French because you have chills going down your spine when you hear the French language, you do.
Strong will is an emotion, not a skill. You cannot practice wanting something very much, but you can have the right reason to which your mind will respond.
Try to work on the reason first. Everything else will make much more sense later.
