A key criteria to be successful in any field is the desire to continually strive to be a better version of yourself. This is very different from the skill of accumulating and remembering facts which may helps in studies and in getting qualifications.

Understand that success is not an accident, but a planned event.

Make sure you work at a place which gives you opportunities to learn, travel, explore, interact with intellectuals and new work skills.

If you play smart, you may achieve your target without using up all your resources.

When nothing works, persistence will.

This is certainly one of the best ways to ensure failure. Make excuses, don't take action!
