FB (or any online or otherwise social networking site) comments are not the epitome of truth. Everything and everyone has positive points. Identify yours, improvise and use them diligently and smartly to become popular. You are NEVER a loser if you choose not to give up; learn to observe,learn and implement; believe change is the only constant so keep changing for betterment NOT for others.
Inference/Moral: YOU ARE NOT A LOSER! BUT learn, understand, observe, implement and change to be WINNER
no it doesn't mean you're a loser. maybe you're just not as popular (that's not a bad thing) as those people who have a lot of likes on their photos. I'm the same. I don't really have many likes on my Facebook photos, but a lot of people I know do.
