Honestly, I think that we could get people to use Bitcoin as a currency by giving away some satoshis for free. This will encourage them to use Bitcoin as a currency, as well as, a store of value for the long term. Also, one needs to explain thoroughly the benefits of the Bitcoin blockchain for average people to become interested in it. Of course, Bitcoin's high fees and slowness prevents it from being used as a currency. But, if the network load remains on a minimum (until the Lightning Network goes full steam ahead), then fees could remain low, while the speed of transaction confirmations doesn't affect itself in the short term.
With good dedication and perseverance, I'm sure that we could get as many people as possible to use Bitcoin as a currency, taking Fiat's place in the future. Hence, the more popular Bitcoin is, the better for us as prices will rise to astronomical levels due to high demand.
