I left my old full time design job exactly three years ago now. WOW! it's gone so fast, it's been a crazy & exciting roller coaster but I've loved every minute. Lots of long hours (& sometimes very stressful times) but I genuinely love my job, so some days it really doesn't feel like work at all (I'm very blessed & grateful to have worked with lots of great people & projects)
I took the plunge & I'm so glad I did! I've never looked back. I always think you might as well as give something a 'try' to at least know you gave something a go... than to have regrets about never trying something. Since setting up on my own as a freelancer & building up my own company it has given me lots of courage to just go for things! So sometimes if you are unsure about something it can really pay off to just go for it. I think it's good to know you have at least tried (even if it doesn't work out, you can learn from it) & taken the odd risk now & then. It keeps it all exciting!
Life is an adventure:)
