You will learn

After a while you start  accepting your defeats with your head held high and your eyes open wide, with a woman"s sublimity not with a child's sadness

You learn to build all your ways depending on the present  because the land of tomorrow is untrustworthy to make plans. 

After a while you learn that even sunrays can burn if you exaggerated in approach.
So , you will cultivate your garden and adorn your soul by yourself instead of waiting for someone to bring you flowers.

You learn that you really can withstand. 
You are really strong , and you enfold your value within you. 
You learn and learn, with every adieu you will learn.

It's a lovely well written poem. Well done. 

Your main mistakes are not using capital letter and punctuation. 

As you were using poetic language I was hesitant to correct some words that I would normally have changed if it were prose. I have highlighted "exaggerated" as I wasn't sure what you meant. If you meant approaching or going out in the sun then I would change it to something like "...if you are overly bold in approach" assuming that you mean that you are bold in going out in the sunshine.
