Just a little bit.
Because these little improvements add up to big improvements over time.
Look, it’s almost impossible to improve by a lot in only one day. But a month? A year? 5 years? 10 years? You can improve drastically by doing a little bit every day.
And the key here is every day. It requires consistency. You can’t just do something once or twice willy-nilly and hope it improves. You need to do it consistently hundreds or even thousands of times.
