If you walk all day long every day as fast as you can, stopping only for meal breaks and bathroom stops, and only stop 8 hours for sleep, how long to walk one light year? It couldn't be done in one lifetime could it?

A light-year is more than 5 trillion miles!! But let's just use convenient estimates for this problem.
Assume: 1 ly = 5 trillion miles
Auusme you can walk at 5 mph, which is a pretty brisk pace.
If you NEVER stopped walking for anything, it would take 1 trillion hours:
(5x10^12) miles / 5 mph = 1x10^12 hours
1 trillion hours is about 114,155,251 years!!
[(1x10^12) hours] / [24 hours/day] / [365 days/year]
So your answer is definitely not!

A light-year is about 5,879,000,000,000 statute miles. This is the distance that light travels in a year. If you could walk at 5 miles per hour, it would take you 1,175,800,000,000 hours to walk that distance. This is equal to 48,982,500,000 days,
which is equal to 134,198,630 years. In other words, if you could walk, non-stop, at 5 miles per hour, it would take you over 134 million years to walk the distance that light travels in one year.

based on the speed of light of 186,000 miles per second (186,000 x 60 seconds x 60 minutes x 24 hours in a day x 365 days in a year), light can travel ~3,776,544,000,000 miles in one year, there are 8766 hours in one year, and the average person can walk 3 miles in one hour, that's 26,298 miles in one year. it would take 143,225,872.7 (rounded to the nearest tenth) years to walk the distance of a light year.

In round numbers: 186,000 miles per second x number of seconds in 1 year!
60s x 60m x 24hr x 365 days = 31,536,000 seconds per yr.
186,000 x 31,536,000 = 1 light year
You won't make it.

It would take one heck of a long time.
You'd better get started post haste !!

It would take hundreds of millions of years.

If you do 3 mph, it would take you roughly, 335,271,600 years.
