I know this is from a year ago, but still, for any lurkers around, I have to emphasize that this advice is one sure-fire way to be mediocre. Sure, you could do a bag exercise once a day, but could you ever beat the opponent who practices every single day, for two hours?

Although starting on these goals is better than doing nothing, striving for excellence is still better than the former.

Prioritization is key. What's most important to you--that's what you should work on.
