Anyway the point I am trying to make is that as an engineer you either have the choice of working for an employer and living an albeit comfortable life (without any risk) or going it alone or starting your own venture with all its associated risk/reward profile.
You have already indicated that you believe in this adage and took the necessary steps to increasing your worth and would continue to take the same approach in future.
What somebody is worth is what the market is willing to pay for them either in salary or by investing in their venture.
