1. Perseverance: Anything you start, make sure you pursuit it to the point of exhaustion. Only then you will feel the full satisfaction of a complete try for the best; 2. Happiness: No point in being successful if you don't enjoy it; 3. Luck: Yes, fortunate or unfortunately - like most things in life - a bit of luck is required for success. Being at the right place or doing the right thing at the right time always helps.
