I'm ex-mil with an attitude problem as Gymble states.
I've always thought paying a second mortgage to end up doing something that is your dream was a nonesense.
However, times have changed and £50,000+ (minimum for a CPL(H)/IR), really isn't that much anymore is it? What can you buy for this these days. A second hand BMW, a shed on the beach at brighton, 2 x heart bypasses?
If you have the tenacity / cash / time / support from your partner....do it...it's a blast up here!!!!
Make sure though, you don't end up working for a dickbreath like Gymble.
