You really don’t need to do any of this right now. You can just wait a bit and it should confirm on it’s own. It would have already confirmed, but the Bitcoin network seems to be a bit full up on transactions at the moment.
I wouldn’t advise you waste the miner fees to speed up this transaction nor create more transactions which will just slow the network as a whole. This is just something people use to increase the priority of their transactions when the network is running at it’s full capacity if they are in a hurry.
