Just like everyone else, you’re only in control of your work ethic and choices. Neither life nor baseball is fair in the distribution of gifted attributes and lucky/unlucky breaks.
If baseball is a passion, then out work everyone else and use being overlooked as fuel – but there’s never a guarantee that translates to getting on the varsity field. However, if do you learn to outwork your competition, use setbacks as fuel while making good choices, that can translate to a foundation for lifelong success.
