Remember Tom Sawyer and his famous fence? He turned a boring task into something all the kids wanted to do. That little story holds a big truth about raising children.
Children don’t need constant rewards to do the right things. When we pay them for chores, grades, or “good behavior,” we quietly signal that those tasks are unpleasant and need bribing.
Instead:

Help your child discover intrinsic motivation — the joy of learning, growing, and contributing. - Offer encouragement that’s genuine and not bargained for in advance — a smile, a hug, a “thank you.” - Show that being responsible is part of being proud of yourself, not just a way to earn prizes.
A surprise reward here and there can be delightful, but what truly lasts is when children see work and learning as opportunities to become stronger and more confident.
The real gift we can give our kids is not stuff, but the belief that they are capable of mastering challenges — even on the days they don’t feel like it.We remember how Tom Sawyer was promoting painting the fence – from a boring job he turned it into something peers were ready to pay for.
Assumption – people want to work, work is a way to realise their potential.
Never use rewards to elicit a behaviour – paying for doing the chores, for studying, for expected behaviour.

Random rewards that were not agreed in advance can be used to encourage behaviours.
Develop intrinsic goals, self-motivation
– Anton Suvorov – by offering a reward for doing some job you signal that the job is undesirable.
Being a professional is doing the things you love to do on the days you don’t want to do them.
– people who aim for extrinsic things – cars, houses – do not achieve satisfaction, happiness when they get those things
People who aim for self-development achieve happiness.
