oh, dear scarlet...it must burn you so to be wrong. i do, however, suggest to you that this is one of those times, my dear.
Can you? The answer to this question is not always YES. It is sometimes---quite often, in fact---NO. Not everybody has the talent to do this. It is not up to the individual. Some could try for eons and still not pull it off. Some are chasing dreams that will not pan out. Some are too shitty to write for a living no matter how hard they try. you must consider talent, silly girl. effort is not the only factor.
Talent comes with effort. Effort comes with desire.
No, this isn't one of those times when I'm wrong. It happens, but not this time.
I've had conversations with people before who say "It's all right for you because..." then they give me a list of reasons why it's so easy for me to do this, that and the other.
To refuse to acknowledge desire, effort and yes, talent, is to devalue the work I've put in up to this point. It didn't 'just happen'. I worked for it.
No, I'm not making a fortune by any means, but what little success I do have isn't down to chance. It's down to me working for it.
The harder you work, the 'luckier' you get.
ETA: If it was all down to talent, none of us would have to practise. None of us would need to be here now, because it would be inborn.
