如果你试图取得成就，就会遇到障碍。我遇到过；每个人都遇到过。但障碍不一定会阻止你。如果你遇到一堵墙，不要转身放弃。想办法爬过去，穿过它，或者绕过它。
If you're trying to achieve, there will be roadblocks. I've had them; everybody has had them. But obstacles don't have to stop you. If you run into a wall, don't turn around and give up. Figure out how to climb it, go through it, or work around it.
