Putting that tattoo on you without warning you what was going to happen is just wrong. I wouldn't go back to that shop.
Everybody's skin is different; there is no way to tell if it will last one year, three years or ten years. Enjoy the tattoo right now. There is NOTHING you can do now anyway. And forget about learning to tattoo.
Other than shaving your chest hair for the appointment, what maintenance do you think you'll have to do? I put cocoa butter on my tattoos a couple times a week, but that's it; any many people don't even do that.
If you do this make sure you get someone really good at script. It's not easy, which is why you see so much really awful script. Do your homework or you'll wind up with a mess.
As @gtrjunior said, too early to tell. I wouldn't go back to that tattooer or shop under any circumstances though, that artwork and line work is really rough. If you need a touch-up after it's healed, find someone really good.
You have more of a chance of F***ing it up than making it better if you start monkeying around with it. Go see a really good artist to get some ideas of what to add around it.
There's nothing wrong with that tattoo.
I've found that the older I get the more it hurts - everywhere. I'm not looking forward to my other ribs. The first ribs hurt, the second I'm really dreading.
Seriously - what are you expecting to get from this site? You already got opinions and advice. You can't fix a letter so what does it matter what letter it looks like? Are you looking for sympathy because you think you got a lousy tattoo, or validation that the tattoo sucks? I'm just not sure what you are looking for.
Depends a lot on where, some on you. I had my calf worked on last Thursday. It was miserable. My other calf was easy, I thought Thursday would be a walk in the park.
Do you not get that this isn't all about how the tattoo looks? Every time you get a tattoo or get laser removal you traumatize the skin. Do you understand that? Do you get that you could do real permanent damage to your skin and wind up with a tattoo that is NOT FIXABLE? Your skin needs time to heal. You could wind up with a hot mess that can't be fixed. You think you hate this tattoo, go google some people with skin that got fucked up from tattooing and lasering the same skin over and over.
Go see someone who is really good at coverups and make a plan to fix this. Be prepared to spend real money. Adding a little something here and there is just going to make it worse. It doesn't matter how many times you ask the same question, or keep rewording it.
