Meditate everyday, and work on designing spells that serve a useful purpose. Magic is tied with the mind and belief. THat's why choosing a branch of magic to observe can help you create beliefs about what works and what doesn't. And most have rituals to boost magical strength
You will never get superpowers, what you will get is nothing less than the potential to control your fate and all the consequences that come with it.
Magic can set up series of events that are nothing less than...well magical, but it's a subtle force and you really won't look amazing for it.
I hate to tie magic to specific scientific principles because that's a great way to get caught with your pants down the moment they find more about quantum mechanics. In the nineteenth century people might have claimed magic had to do with radio waves. Magic is magic and science is science and the two should not cross or disprove eachother
