You're actually taking me back to physics I did some years back. I love sir Newton because of its practical law and how one can easily understand them with ease using the examples given. Reading it now only makes me relate it to real life actions.
For every action, there is always an equal and opposite reaction.
Every push you give to learning new skills, the skills also gives an opposite reaction also. The money gotten from what you learnt is equal to the amount of time and money you put in getting those skills ✌️✌️✌️✌️
Sir Newton's laws was the best then in physics
Thank you very much
