I really need your quick help...PLEASE!!!

hi everyone..
Please check my writing
is this a descriptive paragraph??
what mistakes are there ?
my regards

Through out our life ,we always meet different types of people. Some we like and may be we do not like some others. But definitely ,there are some who we really admire even if they are few. We keep them deep in hearts and minds .One of those most admirable people I ever met is my elder brother ,Jimmy. He has a great personality and a lot of good characteristics. For instance, I am going to write about two noticeable characteristics which are: his role as member in our family and his great efforts in his practical life.

when talking about his role in our family, three sisters , three brothers and a beloved mom ,it is clear that Jimmy feels that every member of us is his responsibility .To illustrate, he keeps doing his best to support every one of us whenever we need help .Moreover, he tries to lead us the safe shore of life through advice and actions. All that due to his warm heart especially with mother. He never says "No" to her what ever she asked .Accordingly, I believe that is the secret which makes him admired by every one around him. Truly, I can call him the" man of our family".

In the same way, Jimmy is hard worker. His great efforts in job is always remarked and respected by others .He never satisfy with what he had reached. But that does not mean that he is eager or mean. On the contrary, he tries his best to proof himself and to improve his work to benefit himself and others in the same time. Although of all that ,he still the most humble and kind person not only for me but for everyone knew him.

To summarize , Jimmy is one of the most admirable people I ever known. That because of his great characteristics which are difficult to be found in a person within our current life. Therefore, I am proud to say that "Jimmy is my brother".
