<p>*Warning: The following conversation between a fictional man and a fictional rabbit changed my life. Reader discretion is advised.</p> <p> </p> <p></p> <p> </p> <p>Here’s how it played out. Brer Rabbit was pouting about what he had and what he didn’t have, and how he never seemed to get what he wanted. Uncle Remus wisely acknowledged Brer Rabbit and said the following life-changing words – <em>“<strong>It’s not what you got. It’s what you do with what you got that counts.”</strong></em></p> <p> </p> <p>These 15 words changed my life. Seriously. Think about all the possessions you <del datetime="2014-08-11T02:24:50+00:00">have</del> think you have to have before you can make a change in the world. Before you can start your business. Before you are secure enough to start a family. That number is <strong>overwhelming</strong>.</p> <p>Will we ever get enough? No. And neither will Brer Rabbit. But there is a <em>second path</em>, as Uncle Remus points out. And Remus was right. When Brer Rabbit stopped taking and started making, his world turned upside down.</p> <p>We all tend to look around at our houses, cars and bank accounts and think, “what will it take for me to get x new appliance/y new luxury car/z amount of dollars.” Inevitably, our solution is to get the resources to get the new x, y or z. <strong>But this is backwards!</strong> Just like Brer Rabbit, we already have the resources we need to move forward with our lives. It’s not <em>what</em> resources we’ve got, it’s <em>what we do</em> with those resources that will affect our outcome.</p> <p>After hearing this conversation between Remus & Rabbit (shoutout Grandpa for making this decades-old cartoon come to life. I love you.), I took inventory. Inventory of my bedroom, inventory of my car, inventory of my bank account. I sat down with a spreadsheet of my resources and a word document of my goals. After many connecting lines later, I had mapped out what I was going to do with what I had to get what I want. The following year, I co-founded and became CEO of a nonprofit business that paired disadvantaged elementary school students with high school mentors. And looking back? I didn’t need more influence, more money, more <em>resources</em>. All I needed was my co-founder and the guts to organize one of the most effective nonprofits our high school had ever seen.</p> <p>Lack of material want and resourcefulness are two very lucky traits I have, and they’re something that I implore more of you to focus on.</p> <hr /> <p style="text-align: center;"><em><strong>If you found value in this article, it would mean a lot to me if you tweeted @mrpetefreeman & told me!</strong></em></p> <hr /> <p>I’m an innovator.

到目前爲止，我已經成功地拉了標題和鏈接的RSS源！但圖像有點棘手。我的主要目標是將圖像鏈接變成我的代碼中的一個變量，我想我可以弄清楚如何從那裏顯示它，但它的奇怪。它被封裝在一個「content：encoded」塊和一個「[CDATA]」塊中，我不確定如何成功訪問它，它肯定不像其他的那樣工作。我試過「內容：編碼」，這給我太多的方式，其他人返回零。這裏是我的代碼
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict {
//NSLog(@"\nXML Parser:didStartElement:%@\n\t\t\tnameSpaceURI:%@\n\t\t\tqualifiedName:%@\n\t\t\tattributes:%@", elementName, namespaceURI, qName, attributeDict);
element = elementName;
if ([element isEqualToString:@"item"]) {
item = [[NSMutableDictionary alloc] init];
title = [[NSMutableString alloc] init];
link = [[NSMutableString alloc] init];
image = [[NSMutableString alloc] init];
}
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
if ([elementName isEqualToString:@"item"]) {
[item setObject:title forKey:@"title"];
[item setObject:link forKey:@"link"];
[item setObject:image forKey:@"content:encoded"];
[feeds addObject:[item copy]];
}
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
if ([element isEqualToString:@"title"]) {
[title appendString:string];
} else if ([element isEqualToString:@"link"]) {
[link appendString:string];
}
else if ([element isEqualToString:@"content:encoded"]) {
[image appendString:string];
NSLog(image);
}
}
- (void)parserDidEndDocument:(NSXMLParser *)parser {
[self.tableView reloadData];
}
如果有人可以幫助這將是真棒，謝謝！
