The optimist pleasantly ponders how high his kite will fly

The optimist pleasantly ponders how high his kite will fly;

 the pessimist woefully wonders how soon his kite will fall.

Throw your dreams into space like a kite

Throw your dreams into space like a kite,

 and you do not know what it will bring back,

 a new life, a new friend, a new love, a new country.

- Anais Nin

Don't be afraid of opposition

Don't be afraid of opposition. 

Remember, a kite rises against, not with the wind.

You can't fly a kite unless you go against the wind

You can't fly a kite unless you go against the wind

 and have a weight to keep it from turning a somersault. 

The same with man.

 No man will succeed unless he is ready to face and overcome difficulties 

and is prepared to assume responsibilities.
