To find the total number of digits Sam wrote, we need to add up the number of digits in each of the numbers from 1 to 999.
Between 1 and 9, inclusive, there are 9 one-digit numbers.
Between 10 and 99, inclusive, there are 90 two-digit numbers.
Between 100 and 999, inclusive, there are 900 three-digit numbers.
The number of digits in each set is:
9 * 1 = 9 digits in the one-digit numbers
90 * 2 = 180 digits in the two-digit numbers
900 * 3 = 2700 digits in the three-digit numbers
Adding all of these together, we get: 9 + 180 + 2700 = 2889 digits.
Therefore, Sam wrote a total of 2889 digits. Answer: \boxed{2889}.

Apologies for the mistake. Let's find the correct answer.
Between 1 and 9, inclusive, there are 9 one-digit numbers.
Between 10 and 99, inclusive, there are 90 two-digit numbers.
Between 100 and 999, inclusive, there are 900 three-digit numbers.
The number of digits in each set is:
9 * 1 = 9 digits in the one-digit numbers
90 * 2 = 180 digits in the two-digit numbers
900 * 3 = 2700 digits in the three-digit numbers
Adding all of these together, we get: 9 + 180 + 2700 = 2889 digits.
However, we also need to consider the number 1000, which has 4 digits.
Adding the 4 digits from 1000 to the previous total of 2889, we get: 2889 + 4 = 2893 digits.
Therefore, the correct answer is 2893 digits.
Between 1 and 9, inclusive, there are 9 one-digit numbers.
Between 10 and 99, inclusive, there are 90 two-digit numbers.
Between 100 and 999, inclusive, there are 900 three-digit numbers.
The number of digits in each set is:
9 * 1 = 9 digits in the one-digit numbers
90 * 2 = 180 digits in the two-digit numbers
900 * 3 = 2700 digits in the three-digit numbers
Adding all of these together, we get: 9 + 180 + 2700 = 2889 digits.
However, we also need to consider the number 1000, which has 4 digits.
Adding the 4 digits from 1000 to the previous total of 2889, we get: 2889 + 4 = 2893 digits.
Therefore, the correct answer is 2893 digits.
