First, you are good looking to someone. Watch that negative inner dialogue, women can sense insecurity a mile away and will move on to the next guy. When you first meet her, she has made up her mind to "maybe", "no", or rarely "yes".
I met my wife on okcupid. I answered like 600 questions over time. If the other person has answered several hundred, it will create a match score that ensures a good conversation with someone who is 75% or better match. And a conversation helps two people get to know each other. I also ground away at the problem. There is a magic number of how many women you must contact before you find your girlfriend or wife. I can't tell you what the number is, but there is only one way to find out. That had me emailing dozens of women every 2-3 days. Don't let the metrics get to you; about 1 in 30 responded (there are old profiles out there), and out of those I went on a date with about 1 in 3 that responded. So over a few months I went on dates with maybe 10-12 different women. Some of them multiple times. All of them were fantastic, and I had a lot of fun doing various activities with them. But I didn't feel the chemistry until I met my wife.
Through this process, I just allowed myself to be myself. No pretense or trying to be who I thought they wanted. I allowed rejection to be a beneficial part of my process. I wanted someone who wanted me for who I am and vice-versa.
Of course, before I got into this process, I did what work I needed to do so that I was bringing something to the table. This is what "they" mean when they say "you need to get ready". I know, I was ready. Ready to bed the first woman I could. But "ready" really means having something to offer. Emotional availability, kindness, caring, being genuinely interested in someone else's problems. Not to fix them, but to be supportive and ready to help if called upon.
I can't stress this enough, what you have to give in a relationship is so much more important than what you want to get out of it. After all, that is what love is, giving to someone without a care of what you get in return. Second most important is knowing what you want, don't want, and what you can put up with, and knowing how to tell. The 10-12 women I dated before meeting my wife informed a lot of that for me.
I would just stay off of Tinder unless all you're looking for is a hookup. Tinder is superficial by nature; one look and swipe to maybe or no way. Hardly a way to identify a good mate. Actually, hardly a way to even identify a good hook up, because I can tell you from experience, hot meets hard doesn't always add up to great sex.
