IMO, finishing highschool is for people who wish to attend university. I have never once been asked to show an employer my HS diploma, EVER. Let's see where dropping out got me:
Dropped out in grade 11 and worked for Culligan water making $14/hour.
Then worked for Shaw Cable on average $20/hour.
Then sold my car and backpacked through Thailand, Cambodia, Malaysia, Singapore, Laos, for 6 months.
Then came back to Canada and bartended at a resort in Kelowna for $12/hour + tips.
Then joined the army for 3.5 years, did a 7 month combat tour in Afghanistan.
Then released from the army to travel more. Hawaii/Costa Rica/USA.
Then sold car parts for a while at one of RS's site sponsors.
Here's my current status: 27 years old, Army reservist and also work as a commissionaire. Shitty pay to be honest but I love what I do so that's all I care about.
0 debt ~ $25k cash ~ 4 cars paid off ~ chihuahua ~ no kids ~ LOTS of plans
