On the other hand, if you consistently miss the goals,  re-evaluate, and consider setting them a little lower as you will only get discouraged and probably give up. 

改变以下句子语序

On the other hand, re-evaluate, and consider setting them a little lower as you will only get discouraged and probably give up if you consistently miss the goals.

参考译文：另一方面，如果你始终如一地/一贯地/坚持地错过目标，再次评估并考虑把目标设置的更低些，因为不料你会灰心/泄气并且很可能会中途放弃。

as 这里引导原因状语从句，as you will only get discouraged and probably give up 因为你会没有想到的泄气并很可能放弃

主句：(you) re-evaluate , and consider setting them a little lower

上面的三个单词miss , re-evaluate,  consider不是并列关系吧？否则意思不通啊

以上3个单词 属于3个并列谓语成分，属于 并列平行关系，第1属于从句谓语，后面2个属于主句谓语

状语：on the other hand

引导条件状语从句连词:if

从句主语：you

状语状语：consistently

从句谓语：miss

从句宾语：the goals

主句谓语:re-evaluate

连词：and

主句谓语：consider

引导原因状语连词：as

从句谓语：will get 

从句状语：only

从句谓语:discourage

连词：and

从句谓语:give up

重点单词及短语解析如下:

                补充回答：

还有一种理解，就是按照刘老师的解答，把as去掉，因为整个句子缺少主句，如果去掉as 后，后面就是主句了

On the other hand, if you consistently miss the goals,  re-evaluate, and consider setting them a little lower( as多余，应该删掉） you will only get discouraged and probably give up. 

改变为下面的句子:

On the other hand, if you consistently miss the goals,  re-evaluate, and consider setting them a little lower， you will only get discouraged and probably give up. 

参考译文：另一方面，如果你总是与所设置的目标擦肩而过，并再次评估，并考虑将目的设置的更低些，你将会觉很灰心/沮丧并很有可能中途放弃。

(1)状语：on the other hand

(2)引导条件状语从句的连词:if

(3)条件状语从句:if you consistently miss the goals,  re-evaluate, and consider setting them a little lower

(条件状语从句3个谓语动词属于“并列平行”关系

(4)主句： you will only get discouraged and probably give up.

而且修改以后也符合，主将从现的“英语语法原则”

以上句子来自于下面文章

Probably the hardest part of setting goals is the first step of actually deciding to take action!The first barrier facing most people is the incorrect assumption that goals are only for business people. The reality is everyone sets goals mentally throughout the day. There arealways occasions

where something has to be done at a particular time Or in a particular place.Simple examples

If you achieve your goal too easily,it is not high enough to make any significant change in your life and needs to be adjusted. On the other hand， if you consistently miss the goals， re-evaluate， and consider setting them a little lower as you will only get discouraged and probably give up. The aim is to keep

growing，and moving into a more satisfactory position for your particular circumstances.

As you obtain the levels that you have set for yourself,always include a small reward at each point.This might only be a small thing in the early days like a meal out or a weekend vacation.

Remember that these changes will not happen overnight and there will be a period of

time when nothing seems to be happening.This is why the goals need to be detailed and as specific as  possible with a consequence and benefit.

Allow some time on a daily basis to educate yourself on how to make the necessary

　　adjustments in your life.This could include listening to a CD，or reading a book on motivation etc. A simple method to start with could be one goal in the main areas of life to be achieved in

one month,six months,twelve months or five years.Break that down further into a daily,weekly and monthly system.Stay focused and disciplined t0 achieve all that you desire.
