A lot of times as hoopers all we know is basketball, whether it's skill development, lifts, film, playing 2k, discussing the NBA with our friends (which is all fine), BUT sometimes that's all we know. Not only is it all we know, but it's who we become. That's the toxicity, you aren't basketball, you play basketball.
No I don't think working hard and being ultra focused on one thing or one goal is toxic, but how you go about that and what happens in the process of getting to that goal may become toxic.
Experiencing things is important for us as people, not massive trips or experiences but even the little things like walks or talking with your grandfather. When all we think about is "I still have to lift" or "I gotta get shots up tomorrow morning before school", we're not present in that moment. We're sacrificing that moment for something else, we are present.
Think about it, I'm not demonizing working hard and being ambitious. I'm questioning if we have to resort all of ourselves towards it in the process at the expense of other things.
