That is why elders always say that ask the interest of the kid rather than forcing our interest on them. If we understand their interest and if we feel his thoughts are not ok, we should be able to convince them, with our logic and with highlighting the points of importance. Then the interest may change. If still, they insist on their choice we should go with them.
Choosing hobbies as a profession can be the best choice for a person to continue and earn satisfaction. Hobbies can be a driving force for individuals to pursue carriers as successful entrepreneurs. This is something we enjoy doing and none would force you to stop doing what you like to do. So we should encourage our children to pursue their interests without thrusting your opinion on children.
However, if we force our children for a particular field, the consequences will be disappointing not only for children on whom we thrusted our opinion but also for the parents who forced them to choose what they felt uninteresting.
Forcing a person for something he does not relish is always going to bring adverse reactions.
Thoughts exchanged is knowledge gained.
