Necessity is the mother of invention. A great thought to ponder on. We humans are very lazy we work to find solutions only after we face problems. But the truth is we should never be satisfied because as soon as we get satisfied we stop working to achieve.
Yes all of us want more. We want to drive the most luxurious cars, use the most expensive gadgets, want admission in the best college or company and might even want to be the world's most successful businessman but will just wanting suffice.
What is actually needed is hunger. Try skipping breakfast, lunch and dinner and then going to bed at night. You would not be able to sleep. You would feel uncomfortable. You would feel incomplete. Same must be the case.
Once you get to know what your aim is you should have the hunger to achieve it. The power to work day and night. The zest to work tirelessly. This hunger is the only elevator to success. The hunger that won't let you sleep at night. The hunger that won't let you pass even a day without moving a step forward towards your aim.
Hunger is the best sauce. Just like a hungry person finds the worst cooked dish delicious. The same way this hunger would not let you be afraid of the obstacles that you'll have to face but make those obstacles seem to you as experiences that will enlighten you during the journey.
All you need to do is find that aim which irritates you more than anything else and once you find it. Success isn't far.
