the grass always looks greener on the otherside- but the more u wanna earn the more ur gonna need to spend bit like a catch 22 - stay in your normal job and just do cash at wkends but dont ever spend it wait till u get enough saved by which time u would av a nice little list of bob the builders wanting work done - then take the plunge, i would advise talking through wiv your current boss so he dont feel to agreaved & threatened that u gonna take some of his client base (worked wiv me) then theres always the chance he would give u all the little jobs that arnt ecconmically viable for him, i do it at the mo for anything under £500 and it helps my mate to grow and keeps me in good stead with my clients, any enquiry he gets thats too big for him ,comes to me so we all happy- just try and stay legal so it dont come back and bite u in the arse
