Life through its many challenges and difficulties has a way of stealing our dreams by making them look difficult and unattainable. It is your responsibility to ensure that all barriers and limitations between you and your goals are crushed. Life won't just give you what you deserve only because you desire them. But you will surely get what life has to offer only if you don't relent your efforts. The fact that your previous attempts didn't work doesn't mean your subsequent efforts won't yield positive results. Do you have any laudable goal or dream you want to achieve? Are you looking for job or seeking admission into academic institutions? Do you have business plan or idea that you desire to launch or promote? I encourage you to be persistent and not to relent. Surely you will WIN!
NOTE:
The fact that it's once impossible doesn't mean it will always be impossible. So I encourage you to pursue your dreams relentlessly.
