Nice to see you here @wealthmindset! I'm not much older than you, but I wish I had your thought process back in high school. I feel like I would be much further on than I am now.
Some of the best advice I've heard, no matter how cheesy it may sound, is "Do the hard work, especially when you don't feel like it". It's super easy to get distracted when you are doing something difficult. Fighting the urge to look at your phone or to distract yourself with thoughts will help you build that discipline. Also, consistency is key. The more you do something, the more likely it is that you will do said thing during the day, regardless of external circumstances.
Hope this helps, and hope to see you more on here!
I struggle sometimes with being disciplined and NEED some tips on how to work on that.
