Coz you are a risk. You might be 5hite! A company might invest in you, to have you scoot off, but the primary reason is that you sound like trouble.
Now that may all seem harsh and to be fair, it probably is, but, as someone who does not know you, the alarm bells are ringing already.
The industry does not owe you anything, so calm down and temper the attitude. This is not a sales industry where positive ambition and drive gets you to the top. It is working with people who have been seen as grease monkey's for their whole career, albeit highly qualified grease monkey's (and I'm a greenie!), who generally bond together and respect each other, regardless of which licence they hold. You appear to have learn't your trade at college, but the vast majority of industry have learn't there's through apprenticeships either with the forces or commercially.
I have got more than 20 years in but I am still learning.
Calm down. There are jobs out there, but don't frighten people off before you have had a chance to show what you can do.
