That is probably because the more info you give away, more trust you are creating amongst people as you are coming across as being genuinely helpful and concerned for others. ๐ค
In today’s world, where everyone is busy, the general notion is – Who has the time to help? and Who helps for free? ๐คทโโ๏ธ
So when you share your knowledge or give away information that helps people, they start trusting you. They see you as their well wisher, not a sales person who is out there to sell them something. ๐
Moreover, you come across as someone knowledgable and expert in your field. ๐
Once you have that kind of trust established, when there is something you are charging for, people are more likely to trust that you will be providing quality. โ๏ธ
In fact often it so happens, that people would themselves ask you if you can provide a certain service they require because they trust you and your knowledge already. ๐
Holding on to and gaurding every little info you have, on the contrary, might harm you in the long run. ๐
Knowledge can not be suppressed. Those open to learning will find some source any how and also there are enough people out there who believe in sharing their knowledge.๐ค
So, share your knowledge. Don’t gaurd it! The more info you give away, the more people will buy what you have to give.๐
