Build a boat to cross Pacific in it.
Many ways to comprehend this phrase but lets take simplest one;-Prepare yourself for challenges in life to achieve your goal. You are a sailor in a boat called life. Just as sailors try to achieve their goals and reach for new lands you must also build your boat strong enough to reach your goal.
But remember "Calm sea never make skilled sailors". In similar way you can't reach success just by sitting in a room and reading this blog but picking up a book and start preparing!
Its never late to start but however you are late its better than not ever trying. Learn from your failures.
In school we learn then give exam but life is different we first give exam then learn from them.
Now lets comeback where we left. We must prepare our ship(skills) to get out and sail in the ocean(life) and reach our destiny. We learn from our childhood that "Hard work is a key to success" so lets fill our boat with food(hard work) and sail with the wind. In our journey we will face storms(hardships) but we are sailors who won't give up and keep sailing through them. During a storm we should remember that if we lose hope we will lose everything so we should sail forward fighting the storm. As we know after a big storm comes a sunny day similarly after many hardships we finally get to rest. But its still not the end of our journey. We should know that more and more storms are to come but after getting through them we will finally reach our goal or we can say what we dreamed of.
Remember Bill Gates didn't reach his goal by just sitting but doing hard work. So don't lose hope and give your best.
All The Best!
