You learn a lot more from losing than you do winning, but you’ve got to reflect on why you lost. It isn't always the fault of others/bad luck. Don’t focus on hiccups that you couldn’t control. Instead, think about what you could’ve done better/differently to change the outcome!
It doesn’t matter if you started last year or last month! No spot is promised. If somebody comes back from the off season & is a better player, a harder worker, more dedicated, they can/will take your spot. Playing time is earned everyday in practice. Hard work is the separator!
