Also I know some of you dudes are not going to be happy with me for saying this but sometimes when you aren't able to do something it means you shouldn't. If you are good at writing music and awful at singing, then you get someone to sing for you. You don't put out a beautiful melody with atrocious singing out there and ask everyone what they think of it, if it's just a hobby you keep this bad copy to yourself because you admitted you were bad at it and you know it's bad. People who use RTP and rips know it's not very cool to do so, and they do it anyway instead of just finding someone who IS good (and there are a lot of these people out there who like doing sprite shit but don't have the patience or skill to do the programming bits). If you know you're using awful junk in your game, you can't be defensive when people call you out on it being bad--you made that decision to leave it in there.
So what you're saying is, if you suck at something, don't do it? (Paraphrased)
What a defeatest additude...
We're not all born with the abilities to do things, such as sing or write music... that does not mean, however, that we should just give up and do what we're good at...
Its like saying "If you can't draw, don't bother..." practice makes perfect, four years ago I couldn't even type 20 wpm with the hunt and peck method of entering keys... but because of practice, I'm now hitting 50 to 60 wpm... depending on if I'm not making errors and backspacing. I wouldn't have gotten to this point without that practice period.
Sure, not everyone can sing... not everyone is born with that talent... but if you spend your time practicing singing, you're eventually gonna get good at it, it might take you years, but you'll get good at it.
Yes, there's also limitations, such as tools and other items. But heck, even with MS paint, you can make a great looking sprite or tileset, but it takes time, effort, and PRACTICE (broken record... oh god, my teacher's rubbing off on me!)
You can say what you will, but the fact remains.
"If you shoot a target and miss, you'll know where you need improvement, if you don't take that shot, then you're always gonna miss"
Edit: Vell, read my post above this one... and JM, Vell beat you too...
