There’s a lot of Stallions who are willingly going to lap up the water you present them. When they are thirsty, they will come.
Pull along a person who doesn’t want to “drink” and they end up sometimes resenting you or brushing you off all together. At best you may receive a “I am glad you believed in me when I wasn’t so sure of myself”
Two final thoughts:
1) There are those who are ready to be “led to water”. Focus on those people if you are in a capacity to do so. Your experience and theirs will be so much more rewarding.
2) Sometimes “forcing the horse to drink” is more about you seeking self worth than it is about them. Perhaps worry more about doing great things as an example to the same horse you are trying to pull.
