I think it applies to you as well. You are taking a risk(settling down on a lower monthly salary and time) which you had no real need to. If the start up flops you end up loosing money and time.
If this happens with 2 or 3 start ups you would have lost a lot of money and time.
I imagine the success chance would go up quite a bit if one does basic things like being persistant and reading up on the wisdom of others.
