I know how it feels. Checkout https://steemit.com/steemit/@steemladder/a-thumb-rule-for-steemit-minnows-50-100-200-25 for some tips.

In short I would suggest you not to make detailed posts initially if you feel that they are not getting the attention they deserve. Instead find users whose posts are making money and users who interact with their users. Start posting meaningful and insightful comments on posts by such users. You will get upvotes if your comments are adding value. Once you gather enough followers you can start making full on posts.

By the I have upvoted your comment and some of your posts. Don't throw your towel yet. Not everybody needs to be content creator on this platform. You can be a reader(consumer), you can add to discussions in comments and so on. Just find your niche. And if you are really serious buy some steem and convert it to Steem power. That will give you more influence.
