I have always found and believed people with a great attitude, capability, focus, discipline and determination succeed and make their own good luck.
I am a 40 yr old college graduate with numerous learnings along the way both from the classroom and on the job. Post secondary education can help provide capability but is also a test/indicator whether someone is able to learn new, complex topics, make good decisions, the all important etc and can provide a glimpse of the possible future. How students applied and projected themselves during the education process and interview/relationship building process determines whether they get employed. As experience grows, we are still students and the same applies.
I also don't beileve it's always necessary for everyone to have post secondary training. Everyone is different with their goals and needs.
As the saying goes - whatever floats yer boat!
