Whatever you do needs to come off as genuine. Some sales people use their humour and likability to sell, others try to come across more professional and trustable. I guess to some extent it depends on what you're selling too, but I don't think all sales techniques would work well for all people. If you look like you're trying to run a sales routine on someone they'll see right through it. I'm not great at sales, but for me working in a computer shop when I was younger helped me a lot. The key I found there was understand the customer's needs and reassuring them that you know what the right product for them is. If you know what you're selling and have confidence in the products you're recommending the customer will be likely to trust your judgement. But I guess this wouldn't apply to all sales. I had the luxury of the customer already looking for a product so I was really just there to assist and reassure them. If you're cold selling my guess is that your personality will be far more important. In those cases you'll need people to first like you enough to hear you out. As someone who's introverted and a bit socially awkward I doubt I'll ever be great at that side of sales, but I'm sure a little door to door sales or similar would go a long way if I ever wanted to practise that. A lot of sales is just good social skill though. Just trying to start and hold conversations with strangers would probably give you 90% of what you need to be a good sales person.
