In startup, if you fail you dont lose 4-6 years of your life. Moreover people wont consider you a failure if you fail in a startup, as opposed to say landing up in a prison.
This is such a stupid comment, I don't know where to begin. Possible attacks on your argument:
1. "set for life" - not necessarily, plus you would have to sell the drugs, etc.
2. just lose 4-6 years of your life - criminal penalties likely greater
3. horrible effects of prison on your psyche and future work possibilities
4. possible death from involvement w/ criminal underworld
5. with a start-up you get transferable experience
Other reasons why this is a stupid comment:
1. Learn to spell succeed
2. Learn to spell lose
If you are not a native speaker, I apologize for #1 but #2 can be corrected with a spellcheck plugin. But it seems like you just typed quickly without thinking your comment through.
