Perfect 50 because I didn't care about school after thinking I found my calling and put my complete focus on that, which got me into the college through early entry as a result even though I found to hate the college later on.
If you want motivation, you need a 'chosen one moment' that comes from a revelation that you are receptive to experiencing, actively pay attention to it not by forcing the empathy in order to feel a sense of significance, but actually let go into actually feeling its genuine significance.
I'd recommend that making the decision as for what you wish to be significant, whether your calling is to be with doing well in school, business, or a creative endeavor, to develop a personal relationship with your inspiration that gives off a grand/significant/otherworldly presence.
Lastly, don't have your interests be distracted by other interests, make this personal relationship with the thing that feels to be your calling as the only thing you *focus* on without distraction.
Ignore anything that has nothing to do with this particular life story that you are the main character of, and that main character archetype/role you take on also comes from an inspiration of a vision for an ideal self, and you'll be able to master anything to the degree that you are a force of nature within the field of interest.
For example, today I found my calling.
I want to be rich, but I do have the tendency to be distracted by my thoughts, however, the things I think about often I find have to do with history, human nature, organizational systems, and stories.
Economics have an inclusion of all of these explorations, and just as how I have managed to create a fully comprehensive mindmap of human nature, so I would like to do the same thing for money in general.
Now, as for strategy in order to do things efficiently, best to have a clear vision of what sort of goals need to be cleared in order to become a master/force-of-nature, such as how I'm right now looking into what sort of job I would like to get in order to learn from experience much faster than I would simply philosophizing or daydreaming based on expectations of the reality; going through the reality firsthand.
Wisdom needs to be put into practice. I think I might be going into real estate, and for that to happen, I need to study as much as I can and increase my current lack of wisdom towards the skills that I personally lack, such as finance, economics, real estate terminology, and how to get a job interview.
There will be a grinding period of studying beforehand before any of your wisdom can be put into practice, for example, you can't do a test on medicine/being-a-doctor if you don't know anything about it.
In this example, you would need the fundamentals, such as how the body works, how or why your body responds to certain experiences and stimuli both with the conscious and subconscious in effect, and common variations between different types of people such as gender or genetic heritage, you will be able to pick up the test and answer some questions.
