I didn’t realize you were only 18! Good for you to already be working on entrepreneurial ventures and earning crypto here on Steemit. That is so freaking awesome.
I have financial goals I am working towards as well, but I still avoid being pushy if I can. It may get you sales in the short term, but it compromises the relationship and may hurt sales down the line. I guess it depends if you are working with long-term customers, or if you’re selling things just random people going by. Those might require different approaches.
