Hi there.
This is just my opinion, cause its similar to yours. I am a session bass player, and I'm currently on the road in North America. This life, its great it really is, I get to meet lots of great people such as Finger Eleven, Goo Goo Dolls, Faber Drive, Jimmy Eat World. And all the other great bands I've got to meet while touring. The money is good, not many expenses due to the tour bus and riders (meals and drinks) at shows. Now, despite all this, I'm home in 4 days and when I get there I am re-activating my application and going to be merit listed again (how do I know?, because the Capt. at Toronto CFRC told me he would do it for me after I talked to him). I thought to myself the same thing you did, I want to have a stable job with a stable income, now I could go to Fleming in Peterborough ON for their Paramedic program, but the opportunities, benefits, and yes money are too plentiful in the Forces to pass up. Its an exiting, and demanding job, and that is very appealing to me. There is no money to be made in music anymore. People do not buy albums, everything is downloaded. And the only age demographic with enough money to spend on music (age 14-18 & its their parents money
) just don't care enough to buy the album, they will just Limewire that catchy song in their head. I'm leaving for something better, no doubt.
You appear to have been making a big effort to reach your goal here, good for you. As for what you should do, by what you have told us, CF sounds like a wise choice. And if you really are passionate about it and willing to do what is necessary to get in then thats half the battle won. Just remember (as I'm sure you are fully aware), what you want to go into is dangerous, things happen, and as you said, you have a son and a girlfriend to look after.
Good luck to you, Kyle
