yeah, but say he works at sears at 8.50/hour, 40 hours a week. that's 340 per week. now let's say his shifts are 8 hours long. that's 5 shifts per day. now if he takes the bus to get there and back, it'd take 2.75 each way, so 10 x 2.75 is $27.5 on the commute. now maybe he drives instead and gas only costs 1.70 to get there and back and an average of 36 cents per trip on average repairs. that adds to $2.06 if he drives so $20.60/week. now since we don't know which one he'll take, let's round between the two. that means. $24.05 per week on transport. now assume he hits a small woodland creature once every 3 weeks and has to pay for clean up, that's $25/3 = $8.33 so in total $32.38. let's say he gets a discount on the clothes at sears and buys rnough shirts to provide 2.5 rags per week in the long run, that is 1.2 more rags than he would accumulate if he were teaching guitar. in addition, he would improve his guitaring abilities 2.6% more than he would playing air guitar to the elevator music at sears. however. his soul would slowly be sucked from working for a large company and he would feel 17 times less significant than he would teaching guitar. to make up for this lack of spirits, he would have to spend 1.3 hours a week volunteering at the local soup kitchen. this would in turn increase the risk of an unknown elbow infection, raising medical bills for subsequent years by $5.30 annually. on the other hand, teaching guitar aroudn unexperienced musicians raises the chances of a freak guitar string fatality. this could increase the cost of life insurance by $2.50. now if he plans to go into a career that requires sales, he might be further ahead if he works at sears. in this case, he could find a job closer to home requiring him to walk 5.2 miles less on average per day. this will lead to 0.07 - 0.1 gram of dirt collected by his nostrils during the walk (depending on location). this leads to a high chance of deafening snoring. in this case, hearing will be weakened. walking will in turn become more difficult and guitar playing nearly inpossible. however, without the ability to play guitar, he will be more inclined to take up a new hobby to benefit those with similar disabilities. in the end, it's really up to what he values: world peace or tuna sandwiches.
