The correct answer to this open question is the following.
What I would say to the colonists to have them join me in the fight for independence is the following.
Dear fellow Patriots,
This is the time.
No other time would be as clear to make the most important decision of our lives.
Our freedom is at hand. And I know it would have a price, but the reward is higher. I know that there is a prize to pay, but of course, it is well worth it.
No more grievances. No more absurd and heavy taxation imposed by the English monarchy.
We have rights and it is time to be free. Independence is our right. We have worked very hard and our families deserve a better future.
I invite you to join the fight. We have no option. It is the only way.
America deserves to be free.
We deserve to be free.
With the ustmost respect,
Samuel Adams.
