Good job, Colin.

### Study the changes provided

#### Exercise 1

- No crashes, works as expected. 4 points

#### Exercise 2

- No crashes, works as expected. 4 points

#### Exercise 3

- No crashes, works as expected. 4 points

#### Exercise 4

- No crashes, works as expected. 4 points

#### Exercise 5

- No crashes, but doesn't work as expected. 3 points
- Doesn't handle when `now` is `0`
- Prefer `{...}` over `do...end` for blocks with a single-line body

#### Exercise 6

- No crashes, but doesn't work as expected. 3 points
- Same as above, so I won't penalize you twice for the same thing. +1 point
- Prefer `{...}` over `do...end` for blocks with a single-line body

#### Exercise 7

- No crashes, but doesn't work as expected. 3 points
- The purpose of the exercise was to not add a `puts` in the `each_without_yolo` method. In other words, the `each_without_yolo` method either calls the block with the current `element` or calls it with `"Life is too short"`.
- Nice use of the `each` method :+1:

#### Total

`4 + 4 + 4 + 4 + 3 + 3 + 1 + 3 = 26` :star:
