你大概想表达的意思：
做事情不用追求完美。追求完美会让事情开头很难，会给我们太大压力。有时候应该放手去做，不用担心好和坏。
你说的：
We don't need to be perfect. If we want to do things perfectly, it may become very hard to start, and we may be stressful. Sometimes, we should just do it without worrying the results.
TED原文，超强语言组织：
中文英文
克服优柔寡断一种方法就是把事情做糟一点！
第一句：先摆出总的观点，吸引对方注意
A way to overcome indecision is to do it badly.
indecision n.无决断力;优柔寡断
很多时候，我们想要完美地完成某件事，直到时机成熟，直到我们掌握了所有的技能，我们才开始。
第二/三句，描述追求完美的现状和危害
So often, we want to do something perfectly, we can't start until it's the perfect time, until we've got all the skills.
但这可能会让人望而生畏且充满压力。
But this can be daunting and stressful.
daunting adj.令人畏惧的
所以，不去担心好坏与否，而是直接投入其中，直接去做又何妨？
第四/五句，表达应该怎么做的观点及其好处
So why not just jump into it，just do it however, without worrying if it's good or bad?
这样会让一件事情的开头变的简单多了。
This will make it that much easier to start something.
当你回过头看，你会发现其实大多时候事情也并没有那么糟。
第六句，从反面打消顾虑
When you look back, you'll realize, more often than not, actually it's not that bad.
