Discard high value cards

Discarding high value cards helps you lower your deadwood and might allow you to knock early.

Hold onto high pairs

For the reason above, you opponent might discard high value cards at the beginning of the game. If you manage to draw those, it can allow you to make meld early on.

Pay attention to what your opponent is drawing/discarding

This allows you to: - hold onto cards you think you opponent might need; - discard cards you think your opponent might not need.

Hold onto the middle cards

Middle cards (5, 6 or 7) might help you to build set from both the low and high cards. They also won't get you as much deadwood as high cards at the same time.

Don't be afraid to knock

Most of the times is better to knock instead of trying to go for gin. There is a possibility that your opponent might catch up and undercut you.
