Nowadays you have a powerful camera built in to your smartphone. Are you using it at nets?
I have noticed that players love to see themselves bat and bowl, but they rarely film themselves, unless a coach instigates it. Yet the power of video is great.
When you see yourself bowl a yorker, or hit a four you feel great. When you watch back and spot a technical issue you can go and work hard on ironing it out when you most likely don't believe it when your mate tells you.
So, film yourself as much as you can.
