On your journey and inevitable achievement of great success, bear in mind this trenchant observation of Robert Frost: 

"In three words I can sum up everything I've learned about life: It goes on." 

I like this quote for two reasons. First, it means that no one is indispensable, which is why it's so important that no matter how important or successful we may become, we should be on our toes to remain modest, friendly, and respectful to all. 

The second message I take away from Frost's words is, "This will pass." All things do. For those who suffer, this message is a gift of solace. Everytime, I am faced with a problem - I remind myself - "This will pass," and it gives me solace. i have internalized this mantra and it helps me get through difficult periods. There may come a time in your life, hopefully not for a long while and perhaps never, if you may be so blessed, that either you or a loved one will need to hear this message. At such times remember, "This will pass." It will give comfort.

Ella Wheeler Wilcox wrote a poem on this subject … 

THIS TOO SHALL PASS AWAY 

A mighty monarch in the days of old

Made offer of high honor, wealth, and gold, 

To one who should produce in form concise 

A motto for his guidance, terse yet wise-- 

A precept, soothing in his hours forlorn, 

Yet one that in his prosperous days would warn. 

Many the maxims sent the king, men say. 

The one he chose: "This too shall pass away." 

Oh, jewel sentence from the mine of truth! 

What riches it contains for age or youth.

No stately epic, measured and sublime, 

So comforts, or so counsels, for all time 

As these few words. Go write them on your heart 

And make them of your daily life a part. 

Has some misfortune fallen to your lot? 

This too will pass away—absorb the thought. 

And wait; your waiting will not be in vain, 

Time gilds with gold the iron links of pain. 

The dark today leads into light tomorrow; 

There is no endless joy, no endless sorrow. 

Are you upon earth's heights? No cloud in view? 

Go read your motto once again: 

This too Shall pass away; fame, glory, place and power, 

They are but little baubles of the hour, 

Flung by the ruthless years down in the dust. 

Take warning and be worthy of God's trust. 

Use well your prowess while it lasts; leave bloom, 

Not blight, to mark your footprints to the tomb. 

The truest greatness lies in being kind, 

The truest wisdom in a happy mind. 

He who desponds, his Maker's judgment mocks; 

The gloomy Christian is a paradox. 

Only the sunny soul respects its God. 

Since life is short we need to make it broad; 

Since life is brief we need to make it bright. 

Then keep the old king's motto well in sight, 

And let its meaning permeate each day. 

Whatever comes, This too shall pass away.
