[Hippocrates]

This seems so obvious. It's like asking your manager for a raise and giving the justification that you want a bigger house.

Always be marketing what you can/will/have done for the company to bring value, not what the company can do for you.

This isn't good advice in this case. The company needs assurance you are worth the investment and that means they need to know this will be personally good for you.
