• Take some design courses.
• Find an entry level position in a design agency. 

Good luck.

Your typesetting is absolutely awful. I teach typography and graphic design, and this is worse than anything I've seen from an intro student. You are not optically aligning anything, using boring stock type that everyone already has, and your layouts aren't sellable because anyone could make them in 30 seconds. You are using inch and foot prime marks instead of quotes and apostrophes, bizarre color combinations, and generally producing extremely poor work. Why would anyone spend money on something that is worse than what they could create themselves? Sorry to be so blunt – nothing personal – but I feel you deserve the truth.

Without a joke: I just looked up one of your designs. Adobe is here clearly to blame to accept this into their database. With all respect, 10 minutes in Word, and I will have an asset that is much more eye catching than this one. And as a bonus, I can enter any discount I want.

I wouldn't buy this asset, even with a 50% discount. I will help your account to get rid of assets like this. 

Idem for this: 

Start creating useful designs. Let people modify the message. This asset is basically useless.

I agree with @daniellei4510  that many of your designs are so simplistic that a user could easily design it themselves. The titles are not nearly descriptive enough. For instance this one is titled "red apple": https://stock.adobe.com/images/red-apple/651922614?prev_url=detail.  Searching on red apple returns more than 30,000 results, and yours will be many pages down in the results so Buyers will never see it. Look at how other Contributors are titling their assets in that category. Your portfolio is still quite small. In order to start seeing regular sales, you'll need more unique assets and thorough, descriptive titles and keywords.

If you do not have downloads, you do not have the right assets for what users are looking for, or your titeling and keywording is bad. There is nothing anybody can do for you here.
