Reduce the number of payments and only send/receive large amounts.

Also, check the mempool before you send:

Wait till it has dropped before sending, and you increase the chances that you receive your coins quickly.

The other option is to use another coin. Ask the people who are sending the coins whether they can use litecoin or doge instead. It's cheaper and quicker.
