Code for fun! It sounds crazy, but it is the easiest hack, plan your day with C++, maintain a dairy, keep your codes there.
Start with easiest one, don't run, try to solve basic mathematics problems using code, start with addition, subtraction, then move to equations, patterns etc.
Learn syntax of language, every language has certain set of rules that govern the language, just like grammar in a language, so learn to stick with syntax.
Learn how a variable is stored in a memory? If an integer variable holds 8 bit, what does it mean? Ask questions to yourself.
Explore, don't be a book worm! try to find various resources to improve your skills, follow websites like Geeks4Geeks, W3schools etc.
Use IDE, but once be familiar with real coding platform. Participate in competitions, just don't start anything, 'close the deal'.
Good Luck!
